What this converter does not do
- Results are rounded for display to 8 significant digits; the stored factor is the exact one.
- It converts US liquid measures (gallon, quart, pint, cup, fluid ounce). UK imperial units of the same names are larger and are not used here.
- It does not convert between a volume and a weight, because that needs the density of the ingredient.
