Common mistakes to avoid
- Dividing when you should multiply. Because 1 stone = 6,350.29 grams, the answer should be larger than the number you started with.
- 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.
- Gram (g): One thousandth of a kilogram; the everyday metric mass unit. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
