Unit notes
A cubic meter is the SI volume unit used as the neutral base for the formula. This page uses the US liquid gallon, not the Imperial gallon or US dry gallon.
Common mistakes
Do not mix US and Imperial units unless the page explicitly says so. If the query uses ounce, pint, quart, or gallon, check whether it means a liquid volume unit, a dry volume unit, or a mass unit. This page is locked to cubic meter -> US gallon.
When this page is the right answer
Use it when the source value is already in cubic meter and the target answer must be in US gallon. For a different pair, use full volume converter, US pint to liter, US quart to liter, US fluid ounce to ml, cubic yards to US gallons.
Quick answer
1 m3 = 264.172052358148 gal (US). In reverse, 1 gal (US) = 0.003785411784 m3.

Standard used on this page
Source unit: SI cubic meter. Target unit: US liquid gallon, not Imperial gallon. This matters because pints, quarts, gallons and fluid ounces can refer to different systems in search results.
Sanity check
If your result is off by about 20%, the usual cause is mixing US and Imperial liquid units. If it is off by a factor near 1000, check whether the input was liters, milliliters or cubic meters.
