# Precision

Which measurement is more precise? 9.52 inches 49.8 inches

Remember that precision means how exact a measurement is.
When the units are the same, the measurement with more decimal places is more precise.

9.52 inches is measured to the hundredth of an inch.
49.8 inches is measured to the tenth of an inch.

A hundredth of an inch is a smaller unit than a tenth of an inch. So, the measurement of 9.52 inches is more precise.
