Getting a feel for the scale

Common mistakes to avoid
- Dividing when you should multiply. Because 1 US fluid ounce = 0.029574 liters, 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?
Cooking tolerates rounding to the nearest 5 mL or quarter cup. Dosing, chemistry and pool treatment do not — keep the full converted value there.
