gal(US) to m³ Converter - Gallon US to Cubic Meter

Conversion derivation

Express both gal(US) and m³ in the same base unit m³ (cubic meter), then cancel the shared base unit.

1. 1

   Rewrite gal(US) in the base unit

   $$1\mathrm{gal}(\mathrm{US})=0.00378541{\mathrm{m}}^3$$
2. 2

   Rewrite m³ in the base unit

   $$1{\mathrm{m}}^3=1{\mathrm{m}}^3$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{gal}(\mathrm{US})& =\frac{0.00378541\cancel{{\mathrm{m}}^3}}{1\cancel{{\mathrm{m}}^3}}\times 1{\mathrm{m}}^3\\ & =\frac{0.00378541}{1}{\mathrm{m}}^3\\ & =0.00378541{\mathrm{m}}^3\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1{\mathrm{m}}^3& =\frac{1\cancel{{\mathrm{m}}^3}}{0.00378541\cancel{{\mathrm{m}}^3}}\times 1\mathrm{gal}(\mathrm{US})\\ & =\frac{1}{0.00378541}\mathrm{gal}(\mathrm{US})\\ & =264.172176858\mathrm{gal}(\mathrm{US})\end{array}$$
