Question

The accuracy of the scale used by super bowl scale can be measured by :

Answer 1

You could use calibration weights (purchased online) to check your scale’s accuracy, or you can use ordinary pocket change. I vote for the pocket change (and instant gratification).

Set the scale to zero and weigh a coin or two: A new penny should weigh 2.5 grams (see note below), 2 pennies should weigh 5 grams, and a nickel should also weigh 5 grams. Don’t worry if your coins are not fresh from the mint, but don’t use any that look really old and worn -- when in doubt, try more coins before deciding your scale is off. If a coin or two weighs the correct amount, you can stop there. But those of you who just can’t give it a rest might also like to weigh a whole handful of coins just to make sure accuracy is maintained.
