About Cubic Meter
The cubic meter is the SI-derived unit of volume. One cubic meter equals 1,000 liters. Engineering, shipping containers, and scientific volumes often use m³.
About Gallon (US)
The US liquid gallon is defined as 231 cubic inches (about 3.78541 liters). US recipes, fuel economy, and retail liquids typically use US gallons.
How to convert cubic meters to gallons (us)
1 cubic meter is equal to 264.17205263729591 gallon (us):
1 m3 = (1000 L ÷ 3.78541178 L) gal = 264.17205263729591 gal
Each cubic meter is defined as 1000 L and each gallon (us) as 3.78541178 L, so one m3 equals 1000 ÷ 3.78541178 gal = 264.17205263729591 gal.
Let V(m3) be the numeric value of the same volume measured in Cubic Meter (m3), and V(gal) the value in Gallon (US) (gal). Then:
V(gal) = V(m3) × (1000 / 3.78541178)
Equivalently, divide by how many m3 fit into one gal (liters per gal divided by liters per m3):
V(gal) = V(m3) ÷ 0.00378541178
Or: gallon (us) = cubic meter ÷ 0.00378541178
Examples
Example #1: Convert 20 m3 to gallon (us)
20 m3 = 20 m3 × (1000/3.78541178) gal = 5283.44105275 gal
20 m3 = 20 m3 ÷ 0.00378541178 = 5283.44105275 gal
Example #2: Convert 50 m3 to gallon (us)
50 m3 = 50 m3 × (1000/3.78541178) gal = 13208.6026319 gal
50 m3 = 50 m3 ÷ 0.00378541178 = 13208.6026319 gal
Summary
To convert Cubic Meter to Gallon (US), multiply the value in m3 by the ratio of liters per m3 divided by liters per gal. Equivalently: value_gal = value_m3 × (1000 / 3.78541178). Numerically, 1 m3 equals 264.1720526372959 gal.
Relationship context
You are converting between metric (SI) (Cubic Meters) and US customary fluid / volume (Gallons (US)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 2.641721e+2.
