Understanding Table Salt Conversions

The Math Behind This Conversion

To convert 1 us cup of table salt to gram, we use the density of table salt (1.23 g/ml). A us cup contains 236.59ml, so 1 us cup equals 236.59ml. Multiplying by the density: 236.59ml × 1.23 g/ml = 291g.

US vs Metric Cups: Why It Matters

When converting table salt, the cup size matters significantly. A US cup (236.6ml) of table salt weighs 291g, while a metric cup (250ml) weighs 308g—a difference of 16g (6%). If you're following a recipe from a different country, using the wrong cup size could affect your results. American recipes use US cups, while recipes from Australia, UK, and most other countries use metric cups.

Measurement Tip

Table Salt is typically used in small quantities where precision matters. Use proper measuring spoons and level off with a straight edge. The density of 1.23 g/ml accounts for the standard "spooned and leveled" method—don't pack or shake the spoon.
