Convert kilograms to US or imperial gallons, or gallons back to kilograms, using water, oil, ethanol, or a custom material density.
kg To Gallons Formula
The following formula is used to calculate the conversion from kilograms to gallons.
Variables:
- G is volume in the selected gallon standard; Lg is exactly 3.785411784 L per US liquid gallon or 4.54609 L per Imperial gallon.
- Kg is the weight in kilograms
- d is the density of the substance (kg/L)
To calculate volume, divide mass in kilograms by density in kg/L, then by liters per selected gallon. Match density to the material and temperature. The table uses rounded water density 1.00 kg/L; cooking-oil and ethanol presets are illustrative.
| Kilograms (kg) | Gallons (US) |
|---|---|
| 0.1 | 0.026 |
| 0.25 | 0.066 |
| 0.5 | 0.132 |
| 0.75 | 0.198 |
| 1 | 0.264 |
| 1.5 | 0.396 |
| 2 | 0.528 |
| 2.5 | 0.660 |
| 3 | 0.793 |
| 3.5 | 0.925 |
| 4 | 1.057 |
| 5 | 1.321 |
| 7.5 | 1.981 |
| 10 | 2.642 |
| 12.5 | 3.302 |
| 15 | 3.963 |
| 20 | 5.283 |
| 25 | 6.604 |
| 50 | 13.209 |
| 100 | 26.417 |
| *Assumes water (ρ = 1.00 kg/L). US customary: 1 kg ≈ 0.264172 gal (US). 1 gal (US) ≈ 3.78541 kg (water). | |
What Does “kg to Gallons” Mean?
kg to Gallons is a conversion factor used to convert a quantity measured in kilograms (kg) to a quantity measured in gallons. This conversion is often used in various fields such as cooking, chemistry, and other industries. The conversion factor varies depending on the substance being converted, as different substances have different densities. For example, the conversion factor for water is different from that of oil. Therefore, to accurately convert kg to gallons, one must know the specific density of the substance in question.
How to Calculate kg To Gallons?
The following steps outline how to calculate the conversion from kilograms to gallons using G = Kg / (d × Lg), where Lg is liters per selected gallon.
- First, determine the weight in kilograms (Kg).
- Next, determine the density of the substance (d) in kilograms per liter (kg/L).
- Next, use G = Kg / (d × Lg) to calculate the volume in the selected gallon standard.
- Finally, calculate the conversion from kilograms to gallons.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Weight in kilograms (Kg) = 50
Density of the substance (d) = 0.8 kg/L. For US liquid gallons, 50 ÷ 0.8 ÷ 3.785411784 ≈ 16.510753 US gal; for Imperial gallons, the same mass occupies approximately 13.748078 Imperial gal.
