Common mistakes to avoid
- Dividing when you should multiply. Because 1 ounce = 0.004464 stone, the answer should be smaller than the number you started with.
- Confusing the fluid ounce (a volume) with the ounce (a weight). They are different quantities and only coincide for water by rough approximation.
- 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
