Metric to Imperial Kitchen Converter

One US cup equals 236.588 mL. To convert cups to milliliters, multiply the number of cups by 236.588. For example, 2 cups = 473.18 mL. Metric cups are slightly larger at 250 mL each, while Imperial cups are 284.13 mL.

When converting between weight units (grams, ounces, pounds) and volume units (cups, tablespoons, mL), the density of the ingredient matters. For example, 1 cup of water weighs 236 g, but 1 cup of all-purpose flour weighs only about 125 g because flour is less dense. Selecting the correct ingredient ensures an accurate weight-to-volume conversion.

A US cup is 236.588 mL, while an Imperial (UK) cup is 284.131 mL — roughly 20% larger. A Metric cup (used in Australia, Canada, and New Zealand) is exactly 250 mL. Always check which cup size your recipe uses to avoid measurement errors.

There are 16 US tablespoons in 1 US cup. Each tablespoon is 14.787 mL. So if a recipe calls for ¼ cup, that equals 4 tablespoons, and ⅓ cup equals approximately 5 tablespoons and 1 teaspoon.

The conversion depends on the type of flour. All-purpose flour has a density of approximately 0.529 g/mL, so 1 cup ≈ 125 g. To convert grams to cups, divide the gram weight by 125. For bread flour it's the same, but cake flour is slightly less dense at about 118 g per cup. Use the ingredient selector in the converter for the most accurate result.

A fluid ounce (fl oz) is a unit of volume — 1 US fl oz equals 29.574 mL. A weight ounce (oz) is a unit of mass — 1 oz equals 28.3495 g. They are only numerically equal for water (since water's density is close to 1 g/mL). For other ingredients like flour or honey, the values differ significantly.

There are exactly 3 teaspoons in 1 US tablespoon. One teaspoon equals approximately 4.929 mL, and one tablespoon equals 14.787 mL. This ratio is consistent across US measurements and is useful for scaling spice quantities in recipes.

Yes. For liquid-to-liquid or volume-to-volume conversions (e.g. cups to mL), no ingredient selection is needed. For converting between weight and volume (e.g. grams to cups), select the ingredient from the dropdown so the correct density is applied. Dry ingredients like flour and sugar have very different densities, so the ingredient selection significantly affects accuracy.
