Does anyone know the accuracy of this scale? I'm not talking about precision, which is the .01 g.

I find it to be within five milligrams above or below the unit being measured. That is if you calibrate the scale with the proper test weights, use it where there is little to no interference, etc. However, I find it doesn't measure items unless they weigh at least 30 milligrams, yet air and other things seem to effect it somewhat. Its worth the 20 or so dollars, but don't expect anything above average out of this scale. Measuring out anything that is 30 milligrams seems damn near impossible.

The manufacturer calls the "Accuracy" as the "Acceptable Tolerance" and it is "+/- 0.02 g." Exactly the same calibration standard weight doesn't always read the same number (measurement repeatability). But my 100-gram calibration weight has always read within this "+/- 0.02 g" accuracy. I've found that the "sensitivity", or the "minimum measurable weight", is about 0.03 gram. There is some hysteresis effect to it. That is, after you measured 0.05 gram, then you can reduce the weight to the minimum 0.03 gram. You can't directly measure the 0.03 gram weight without adding some additional weight first, then take away the additional weight. The "reading resolution", or the "Readability" as called by the manufacturer, is, of course, "0.01g."

Get the calibration weights. They are an absolute MUST with inexpensive scales. This one is pretty accurate. I reweighed the same mass 5 times and got the same reading each time.

The accuracy of this scale is 1 g so it will automatically round off to the nearest gram. Therefore it will not accurately measure/recognize the difference between 1.8 and 2.2 g. If you need accuracy to +/- 0.1 g you need a different scale. However for cooking purposes 1g accuracy is all you need.

It's an incredibly accurate scale so you won't have to worry about inconsistent loading, but the scale's weighing dish will only hold about 3 grams of powder. I'm not familiar with how much powder you need to reload the casings/shells you're loading but if you need more than a few grams you may want to get a scale with a larger weighing surface. You probably only need accuracy to 0.01grams for your purposes rather than 0.001g like this scale, but if consistency is your biggest concern then this scale is perfect for you.

The claim is to be accurate to 0.01 g. I have found that it is at least accurate to 0.05 g when I measured it against a standard balance weight, and certainly to the second decimal place when measuring in ounces.

Sorry, but at the end I did not buy that scale, I bought one from another seller.Guess who makes them?: ChinaThe way I found out is to call the seller and ask him a tricky question; like: what about if scale accuracy is not what scale manual states? He will most likely state he will contact the mfr: Bingo!( For your information if the manual says scale has an accuracy of +/- 0.2 pounds of full scale reading, this means for example if you weigh yourself and scale reads 110 pounds +/- 0.2 pounds for a total of 109.8 pounds or 110.2 pounds.So Accuracy is OK. If the deviation is greater, scale accuracy is bad) Sorry, but at the end I did not buy that scale, I bought one from another seller.Guess who makes them?: ChinaThe way I found out is to call the seller and ask him a tricky question; like: what about if scale accuracy is not what scale manual states?

I have compared it to a lab beam scale and it is accurate to 0.5 gram at 6 values between 10 and 500 grams with 1 gram resolution.

Yes it dose measure to .01 of a gram. It measures up to 100 grams also. Great accurate and doesn't tack up a ton of room.

The scale is very accurate to even less than an ounce. The weight is displayed in decimals of an ounce. For example, for lighter items the display will show 0 lbs. 0.8 oz. It operates on batteries that make it very convenient to move.I had it for several months and it's a great and accurate scale. I'm very pleased with it. Rich G. Palm Harbor, FL

Seems to be consistent. As far as accuracy goes I can't say. Certain scales weigh me heavier, others lighter.

I purchased this scale over 1 year ago and it is still very accurate. Most scales are not very accurate over 200 pounds. I weigh about 350 pounds and it still works great for me.

On the grams setting, the scale reads to 2 decimal places: i.e. it will read 0.43 gms but it will not read 0.436 gms. I do not have a way to determine if it rounds up or down in the 3rd decimal place. Hope this helps!

There is no need to calibrate the scale before use. I use the scale to weigh out coffee for my morning brew. The measurement readings change with increases in weight. From 0-200g you're able to measure to the nearest hundredth of a gram (0.01g). From 201-500g your able to measure to the nearest tenth of a gram (0.1g)From 501 - 2000g you're able to measure to the nearest gram (1g)Hope this helps.

gn is for grains, g is grams. If you are using this scale for reloading make sure it is set to gn. You have to use grams (g) for calibrating the scale.I have found mine to be very reliable for a travel/inexpensive scale always +-1gn. As for ct I have no idea what it is for.

David, I doesn't as far as I know. I am from the old school and I never use the gram measurements. I just put a pencil on the scale and said 5 grams. I weighed the same pencil on the Lb. side and it read 0.20. I hope this helps you.

Hello, The scale reads in .1 gram increments, so it will read .1, .2, .3 etc and 21.1, 21.2 etc. Have a great day!

It is extremely accurate. It weighs me the same as the one at my doctors office. I learned of this brand as my doctor office uses only tanita scales.

It does gram accuracy. It shows X.XX oz accuracy on the screen, but I would say it is accurate to the .04-.05 oz, not .01 oz., as 1oz = ~28.3g
