Pan size and capacity calculator
Measure inside your pan to see how much it holds and how big its flat base is. Use inches or centimeters for every measurement.
Estimated capacity to the rim
2.21 US qt
2.09 liters. Leave room below the rim when cooking.
How the calculation works
A round pan with sloping sides is treated as a cut-off cone: V = πh(D² + Dd + d²) / 12, where D is the inside width at the top, d the width of the floor and h the depth. A rectangular pan is length × width × depth. Rounded corners and curved walls hold a little less than the answer.
Quarts, liters and area
One US liquid quart is 57.75 cubic inches, or 0.946352946 liters. One inch is exactly 2.54 centimeters. A flat round base has an area of π(d/2)². That lets you compare how much room two pans have on the floor; how well food browns also depends on the pan and the heat.
Rim diameter versus flat base.
When the maker gives a capacity
Go by the maker's figure when the pan lists one; this calculator is for pans that don't, or for checking what a size means. It doesn't scale baking recipes. Leave room below the rim for stirring and bubbling, and follow the pan's own instructions.
For an amount in your recipe, convert grams to cups by ingredient or switch between cups and quarts. Food that swells as it cooks, like rice or pasta, needs more room than its raw amount.
