Common mistakes to avoid
- Dividing when you should multiply. Because 1 US cup = 236.588 milliliters, 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?
Cooking tolerates rounding to the nearest 5 mL or quarter cup. Dosing, chemistry and pool treatment do not — keep the full converted value there.
