Common mistakes to avoid
- Dividing when you should multiply. Because 1 kilogram = 0.157473 stone, the answer should be smaller 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.
