How to convert Ounces (oz) to Metric cups (250 mL)

Enter your amount in Ounces (oz) and your ingredient density in g/mL, then select Convert. The result is shown in Metric cups (250 mL).

Conversion formula

Result = amount × 28.349523125 ÷ 250 ÷ density

The formula uses the Ounces (oz) factor 28.349523125 and the Metric cups (250 mL) factor 250 in mL and g, with density to connect volume and mass.

Worked example

1 Ounces (oz) ≈ 0.1133980925 Metric cups (250 mL). Reference examples assume a density of 1 g/mL (approximately water). Other ingredients need their own density.

Good to know

US customary cups and spoons differ from metric measures. Converting volume to mass requires ingredient density: the default 1 g/mL approximates water, not flour or other ingredients.

Results and displayed factors are rounded to 12 significant digits. Calculations use the full stored factors.
