Conversion Formula
The formula to convert milliliters (ml) to gallons (gal) is:
gallons = milliliters × 0.000264172
This works because 1 gallon is exactly 3,785.411784 ml, so multiplying by its reciprocal (1 ÷ 3,785.411784 ≈ 0.000264172) converts ml to gal.
Example: Convert 100 ml to gallons:
- Multiply 100 ml by 0.000264172
- 100 × 0.000264172 = 0.0264172 gal
- Rounded to four decimals: 0.0264 gal
Conversion Example
- Convert 250 ml to gallons:
- Multiply 250 by 0.000264172
- 250 × 0.000264172 = 0.066043 gal
- Result: about 0.0660 gallons
- Convert 500 ml to gallons:
- 500 × 0.000264172 = 0.132086 gal
- This means half a liter is roughly 0.132 gallons
- Convert 80 ml to gallons:
- 80 × 0.000264172 = 0.021134 gal
- This is a smaller volume, about two hundredths of a gallon
- Convert 120 ml to gallons:
- 120 × 0.000264172 = 0.031700 gal
- So, 120 ml equals roughly 0.0317 gallons

Conversion Definitions
Milliliter (ml): A milliliter is a metric unit of volume equal to one-thousandth of a liter. It is commonly used to measure small quantities of liquids in scientific, medical, and everyday contexts. One milliliter corresponds to the volume occupied by one cubic centimeter.
Gallon (gal): A gallon is a unit of volume used in the United States and some other countries. The US liquid gallon equals 3.785411784 liters, different from the UK imperial gallon which is about 4.54609 liters. Gallons measure larger liquid quantities like fuel or milk.
Conversion FAQs
Why is the conversion factor 0.000264172 from ml to gallons?
The factor 0.000264172 comes from the exact definition of a US liquid gallon, which is 3,785.411784 ml. Dividing 1 by this number gives the multiplier to convert milliliters into gallons. This precise factor ensures accurate conversions between metric and US customary units.
Can I use this conversion for UK gallons?
No, the conversion shown is for US liquid gallons. UK gallons, or imperial gallons, are larger at about 4,546.09 ml per gallon. To convert ml to UK gallons, a different factor of approximately 0.000219969 should be used instead.
Does temperature affect ml to gallon conversion?
Volume measurements like ml and gallons assume standard conditions. Temperature changes can cause liquids to expand or contract, affecting volume slightly. However, for most everyday conversions, temperature impact is negligible unless dealing with precise scientific or industrial measurements.
Is the conversion factor the same for all liquids?
The factor converts volume units independent of the liquid type. However, if you want to convert mass or weight, density becomes important. For volume-to-volume conversions like ml to gallons, the liquid type does not matter; only the volume units are converted.
How precise is the conversion result when rounded?
Rounding to four decimal places gives a good balance between simplicity and accuracy for everyday use. For very precise applications, more decimal places might be needed. The exact factor has many decimal digits, but four decimals are sufficient for normal liquid measurements.
