In simple terms, a balances measure mass, while scales measure weight. So if you bring a balance and a scale to the moon, the balance will accurately give you the mass of, say, a moon rock, whereas the scale will be affected by the gravity. A balance determines mass by balancing an unknown mass against a known mass.
Does a balance give you mass or weight?
Balances Measure Mass A true balance measures mass directly by comparing the unknown mass to a known mass, a process that is not affected by changes in gravity. A balance of this sort will give the same reading irrespective of location because gravity will act on both sides of the balance equally.

Can a scale be 20 pounds off?
Think about that when you get on the scale after you’ve had a bean salad, soup, fiberful potato and even more water at dinner.

What’s the fewest weights you need to balance any weight?
For any weight w from 0 to 40, add 40, then convert to base 3, and finally subtract 40 by subtracting 1 from each base 3 coefficient. Since w is at most 40 = 1111 base 3, w + 40 is between 1111 and 2222 base 3, giving the base 3 numbers with 4 columns from 40 to 80.
How many pounds can you balance with 1 lb?
So, starting with the 1-lb. weight, which can balance any weight from 1 to 1 pounds, we get 2 ( 1) + 1 = 3 pounds for the next weight, and they can balance anything up to 1 + 3 = 4 pounds. Then, for those two weights, we get 2 ( 4) + 1 = 9, and they can balance up to 1 + 3 + 9 = 13 pounds.
When do you use Class M2 test weights?
Weights intended for use in the verification or calibration of class M2 weights, and for use with weighing instruments of medium accuracy class III (where ‘e’ is less than 10,000) You can now determine the correct class and nominal value of test weights that you require for the monitoring of the performance of your balance (s).
