Getting a feel for the scale
A converted number is easier to trust when you can picture it. These reference points let you sanity-check the result at a glance.
Stone (st)
- Stones are still used for body weight in the UK and Ireland
- 1 stone = 14 pounds
Common mistakes to avoid
- Dividing when you should multiply. Because 1 stone = 0.00635 metric tons, the answer should be smaller than the number you started with.
- Assuming there is only one ton. The US short ton, the Imperial long ton and the metric tonne differ by up to 12%.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Kitchen scales resolve to about 1 g or 0.1 oz, so two significant figures beyond the decimal point is wasted precision. Postage and freight are normally rounded up to the next billing increment.
How these units are defined
- Stone (st): 14 pounds; the everyday unit for body weight in the UK and Ireland. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Metric ton (t): 1,000 kilograms, also called a tonne. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
