Cups to Cubic Meters formula
The factor from cups to cubic meters is 0.000236588236.
m³ = cup × 0.000236588236
Why this factor: the cup and the cubic meter are both defined against the liter, so dividing one definition by the other gives 0.000236588236 directly. Both definitions are set out in full below.
To go the other way, divide by 0.000236588236 — or use the Cubic Meters to Cups converter, which is the same calculation reversed.
Worked example
Given 50 cup, multiplying by 0.000236588236 yields 0.011829 m³.
50 cup × 0.000236588236 = 0.011829 m³
The converter above does this for any value you type, in either direction.
What is a cup?
A US customary cup is the standard cooking volume measure in American recipes.
Definition: Exactly one sixteenth of a US liquid gallon, so exactly 236.5882365 milliliters.
Where it is used: American recipes and baking, where dry and liquid ingredients alike are measured by cup.
Worth knowing: Nutrition labels use the US *legal* cup of exactly 240 mL, and a metric cup is 250 mL — three slightly different cups are in circulation.
What is a cubic meter?
A cubic meter is the SI unit of volume — the space in a one-meter cube.
Definition: Derived directly from the meter. Exactly 1,000 liters.
Where it is used: Freight and shipping volume, concrete and timber quantities, natural gas metering, and HVAC airflow.
Cups vs Cubic Meters
The cup is a US customary unit while the cubic meter is an SI unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
