True or false a scale that measures the mass of an object in grams to two decimal places is more precise than a scale that measures the mass of an object in milligrams to two decimal places

I think it's false because if you measure very little weight it's better to use scale that measures the mass of an object in milligrams to two decimal places.

Essentially, what the question is asking is whether a scale that measures in grams is more precise than a scale that measures in milligrams.

Milligrams are smaller than grams, so if you for example have an object that weights 81,34 milligrams the other weight would only show 0.81 grams - some information is lost!

So yes, a milligram scale is better - the statement is therefore false
