Kilograms ↔ Gallons Converter
Density: 1.000 g/ml (H₂O)
Conversion Results
Conversion Formulas
Kg to Gallons:
Volume (gal) = Weight (kg) ÷ (Gallon Size (L) × Density (g/ml))
Gallons to Kg:
Weight (kg) = Volume (gal) × Gallon Size (L) × Density (g/ml)
* US Gallon = 3.785412 L, UK Gallon = 4.54609 L, US Dry Gallon = 4.40489 L
Common Conversion Examples
| Substance | Weight | Volume | Note |
|---|---|---|---|
| Water | 1 kg | 0.264 gal | 1 kg water = 0.264 US gallons |
| Milk | 1 kg | 0.258 gal | 1 kg milk = 0.258 US gallons |
| Olive Oil | 1 kg | 0.288 gal | 1 kg olive oil = 0.288 US gallons |
| Honey | 1 kg | 0.186 gal | 1 kg honey = 0.186 US gallons |
| Flour | 1 kg | 0.5 gal | 1 kg flour = 0.500 US gallons |
| Sugar | 1 kg | 0.375 gal | 1 kg sugar = 0.375 US gallons |
Density Quick Reference
Conversion Tips
1 kg of water = 0.264 US gallons (room temperature)
Oils are less dense than water, so 1 kg = more gallons
Dry ingredients vary widely in bulk density
UK gallons are 20% larger than US gallons
Understanding Weight to Volume Conversion
Why Weight and Volume Differ
Kilograms measure mass (how much matter), while gallons measure volume (space occupied). The relationship depends on density - how tightly packed the molecules are in a substance.
The Density Connection
Density = Mass ÷ Volume
Different substances have different densities. Water has a density of 1.0 g/ml, making it our reference point for conversions.
Factors Affecting Conversion
- •Temperature: Most substances expand when heated
- •Pressure: Compression can increase density
- •Purity: Mixtures have combined densities
- •Physical state: Powder vs. liquid vs. solid
Note: For cooking and most applications, standard densities at room temperature provide sufficient accuracy.
