You are scaling a cake recipe up by double. The original needs 1.5 cups of water; the tool shows 354.88 ml so you measure from a graduated cylinder instead of guessing.
A food blog gives an ingredient list in ml while your kitchen uses US cup measures. Enter 0.75 to find it equals 177.44 ml, matching the volume on your standard measuring cup set.
Worth knowing
- The conversion uses the US legal cup (236.588 ml), not the Imperial cup (284 ml). Using the wrong cup size gives a result that is about 20 percent too high.
- Rounding to whole millilitres is fine for most cooking, but bakers working with small ingredient ratios should keep at least one decimal place to avoid cumulative error across multiple ingredients.
- The tool displays full-precision output based on the exact factor. It does not round to fit common measuring-cup increments, so results like 177.44 ml may not match any physical measuring cup exactly.
