How it works
Enter a value in US liquid gallons. The tool multiplies by the exact definition 1 US liquid gallon = 3.785411784 liters.
Results update as you type (light debounce) or when you press Convert. Empty input clears the result—no error. Non-numeric input shows a validation message instead of a wrong number.
Displayed values keep up to 10 decimal places and drop trailing zeros so precision stays useful without looking over-rounded.
