How Much Is 100 Grams of Olive Oil in Gallons?
100 grams of olive oil equals 0.03 gal. Olive oil has a density of 216g per cup. Because grams measure weight and gallons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 100 grams of olive oil
- 1 cup of olive oil = 216g
- 100g ÷ 216g/cup = 0.46 cups ÷ 16 = 0.03 gallons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Gallon?
For large-batch cooking, 1 US gallon is approximately 3.8 liters. The imperial gallon (4.5 liters) is no longer commonly used in the UK for cooking, as most modern British recipes use metric measurements.
