Cubic Meter Calculator

Enter nonnegative side lengths in meters.

$\text{m}^3=\text{length}\times\text{width}\times\text{height}$

One cubic meter is exactly 1,000 liters. From the exact international-foot definition, 1 m³ = 1 ÷ 0.3048³ = 35.314666721488… ft³. From the defined U.S. liquid gallon, 1 m³ = 1,000 ÷ 3.785411784 = 264.172052358148… US gal.

For 2 m × 1.5 m × 1 m, the result is 3 m³, 3,000 L, about 105.944 ft³, and 792.516 US gal. Inputs producing an invalid numeric result are rejected.
