What this volume conversion is for

Use this page when a measurement is written in gallons and the next step needs liters. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

10 gallons are 37.85411784 liters. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.

The reverse conversion is liters to gallons. A nearby pair in the same units is gallons to pints. When the converted number is the input to a job, continue with the volume of a tank.
