Why You Should Use A Milligram Scale

Nootropics Depot always suggests using a reliable milligram scale for measuring powder doses as scoops are highly unreliable for measurement. Nootropic and natural extract powders have different densities and therefore generally shouldn't be measured using a scoop.

Scale Accuracy, Resolution, Precision, and Capacity

The terms accuracy, precision, capacity, and resolution are important concepts when talking about the properties of a scale. Although the terms have distinct meanings, many times people confuse them with one another. When an object is placed on a scale, the scale responds by displaying a measurement of that object's weight. The confidence in knowing how close the displayed weight is to the actual weight depends entirely on the accuracy, precision, and resolution of the scale at a given weight. Let's look at each one individually.

The resolution of a scale is the smallest increment in measured weight that can be displayed on the scale. The NDS-201 is a milligram scale. Therefore, the smallest unit the scale can display is 1mg. This is also the amount the scale increments or decrements by when weighing. The NDS-201 cannot measure fractions of a milligram. To measure fractions of a milligram, you would need to move to a 0.1mg or 0.01mg precision balance, and those run into the thousands of dollars per scale.

The accuracy of a scale is how close the value of an object's displayed weight is to the object's actual weight. If a scale indicates that a 10 gram weight weighs 10.005 or 9.995, then the scale is accurate to within 0.05% at 10 grams, or a 5mg deviation. This is the maximum amount the scale would deviate from the actual weight value of an object at that specific weight. This accuracy of a scale is different at various weights as well. This is due to the resolution of the scale affecting how close it can get the displayed weight to the actual weight of an object. Since a milligram scale has a 1mg resolution, and you cannot display fractions of a milligram, the accuracy of the displayed weight will be lower at lower weight values. Let's say we are measuring 50mg instead of 10 grams. If we wanted an accuracy of 0.05% at 50mg, the scale would need to have a resolution of 0.001mg, or one microgram. This is an incredibly tight tolerance, and microgram scales run tens of thousands of dollars to achieve that resolution. So that accuracy level is impossible at the 50mg level on a milligram scale. If you weigh a 50mg weight and get a value of 48mg or 52mg, then your scale is accurate to within 4% at 50mg, or a 2mg deviation. What this means from a practical standpoint is that your milligram scale gets more accurate the more weight you put on it.

The precision of a scale is the measure of repeatability of an object's displayed weight for multiple weighings of the same object. Essentially, precision is the deviation or fluctuation of the measured weight of a single object across multiple instances of weighing on the same scale. If you weigh a 10 gram object 5 times, and you get 10.005, 10.001, 9.995, 9.999, and 10.000, your precision is 0.05%. This is because the maximum value of deviation (5 milligrams) from the average of all the weights (10 grams) is 0.05%. Think of precision as a measure of how much a scale's weight display will fluctuate from one time to the next.

Finally, capacity is the largest weight the scale is capable of weighing. The NDS-201 has a capacity of 20 grams. This means that the maximum weight of an object you can put onto the scale is 20g. Not only is that the maximum it can accurately weigh, but it can also damage the mechanism of the scale by going over that maximum capacity.

  • Sergey Rezakov - 8th Apr 2022

    Works good, decent quality. Doesn't look or feel cheap.

    It was my first time buying a scale and I am happy I bought it. Helpful purchase. Helped me to finally start using bulk powder supplements

  • Jonathan - 23rd Mar 2022


    Good form factor. It seems to have no span control, to adjust calibration, only tare (which is actually its zero, electronically), so when I noticed that it was no longer linear I ordered another, they're cheap. If it does have a span control I'd appreciate being told how to adjust it. I guess I'll be buying another, soon.

    Great scale

    Scale works great. A must have for anyone buying powder.

  • Austin - 3rd Feb 2022

    Best scales I've had

    Great scales very accurate and user friendly

  • Alexander - 26th Dec 2021

    Milligram scale

    Honest to God this is the best scale I’ve ever had! I used to order my scale from Amazon but after a few months they kept breaking on me. I use my skills more frequently than I should. Whether I’m in the lab or no at home I’m always experimenting with something. Except for the last one I accidentally stepped on it, that’s on me. But after seeing the great reviews on the scale and how well it was calibrated I knew I had to take advantage of it! I’ve been using it for the last two months and it hasn’t bugged out on me nor has it giving me poor measurements. Always accurate each and every time! It’s very prestige and I give it to nootropics depot for creating notches a great looking skill but an actual functioning one with all the bells and whistle‘s that are needed. Highly recommend if you were in the market for a new scale and want your moneys worth!

    Can't Recommend

    This is the 3rd scale I've purchased through Nootropics Depot. Each one lacked durability. The last scale I purchased became non functional by the second day. The weighing pan is too small. The indented weight plate makes this scale inaccurate if you use a larger weigh pan to mass out larger amounts of product. There are better scales like the Gemini 20 or the Newacalox at the same or lower price point. ND Admin: There is a lifetime warranty on the scales... We would have replaced it for you for free; especially at day 2. Furthermore, these are made in the same factory as the Gemini-20. The weighing pan is literally the same size. Also, that scale is $49.99 on Amazon right now, and doesn't have a lifetime warranty. It's double the price for a worse warranty, the same size weighing pan, and literally made by the same factory as our scale. We also have a larger weighing pan you can add to the order now, which is not even an option with the Gemini-20. We also test and calibrate every single scale before sale, which neither of those other brands do.

    Pretty good scale

    The accuracy leaves a bit to be desired, but I can't complain for the price!

  • Alex Kurbiel - 11th Aug 2021


    Great product, works very well for the price!

    depot milligram scale

    The suggestion to place it on a metal surface made a big difference. I had started with placing on my old wooden desk, but the readings were unsteady. On a metal box it was much better. This item is a little flimsy, not crisp in its accuracy, but met my needs for supplements. If your need is super accuracy, you might want to get a higher quality item. But this one is very good for the casual user, good for the price.

  • Evan - 12th Jun 2021

    Great Product

    This scale is very accurate and high quality. I use a piece of tin foil or a post-it note to expand the volume capacity of the weigh pan.

    Nootropics Depot Milligram Scale

    I gotta say, I've had a few mg scales over the years and this is quickly becoming a favorite. Excellent accuracy, ease of use, and the 10g weight are a few of my favorite elements. Very reasonable price. If you buy one, I recommend getting the extra tray they offer at checkout. That comes in handy!

  • kazarnyc - 9th Mar 2021

    Handy, good for the price

    I purchased this scale to weigh out supplements that I buy in bulk rather than in plastic bottles. For this application it is certainly accurate enough, and the price is right for what you get. I subtracted one star because the tray is too small to contain, for example, 2 grams of creatine. Your choice for weighing fluffy powders in amounts that exceed the capacity of the tray is to measure in two or three parts, or to balance some kind of bigger cup atop the tray (and use the tare function). If the scale came with a bigger cup that fits inside the tiny tray, I would give 5 stars.

    Very happy with this purchase. Fills my need perfectly.

    Has worked really well for weighing my supplements. And its nice to use.

    Milligram Scale NDS-201

    I have a scale (SWS100) that can weigh to 0.01 gram accuracy. That accuracy is not good enough for some of the powders I use, so I purchased the NDS-201 scale that has 0.001 gram accuracy. Things I like: product is compact; the calibration weight is conveniently located within the product's case; the scale is easy to use; calibrating the scale is easy; the manual is clearly written (for me) and the instructions for use and calibration are easy to follow. Things I don't like: the stainless steel weighing pan is loose within the scale case (I've been spoiled by the fact that the SWS100 scale has a permanent 'platform' on which to place your powder or your own measuring container); no instructions are printed on the scale or case ... front or back - the manual needs to be somewhere convenient in the event it is needed (again, spoiled by the SWS100 which has instructions inside its lid). Having said that, I needed to download the NDS-201 manual from the internet because I had already misplaced the original! But this is a plus, because the manual IS actually available to people like me! Overall I am happy with the NDS-201 scale. I have no problem recommending this scale to others because of the scale's performance.

    Complicated to figure out

    This is complicated to use and program if you’ve never used one before. The product it’s self might be fantastic. We just had a difficult time knowing if it’s even working correctly because we’ve never used one before.
