Why does tablespoon size vary between countries?

Different countries use varying standard measurements for a tablespoon, such as 15 mL in many metric countries and 20 mL in Australia, which affects volume conversions.

What is the exact volume of a US customary cup?

The US customary cup equals 236.5882365 milliliters, commonly used in cooking, although some nutrition labels use a 'legal' cup defined as 240 milliliters.

Can I use this conversion for weight measurements?

No, this tool converts volume units; weight conversions depend on ingredient density and require separate calculations.
