Converting a measurement to another unit changes the amount being measured.

### Why this is right The statement is false because conversion changes how an amount is expressed, not the amount itself. For example, a length can be written in metres or centimetres while remaining the same length. ### The concept A unit conversion uses an equivalence between measurement units. The numerical value changes in the opposite direction to the unit size: the same length has a larger number of centimetres than metres. The physical quantity itself is unchanged. ### The concept This distinction is essential when checking calculations. A result with a new unit should still represent the original quantity. ### Terms - **Conversion**: changing the unit used to report a quantity without changing the amount. - **Unit**: a standard used to express a measurement. ### Remember A conversion changes the label and numerical value, not the measured amount.
