Frequently Asked Questions
Common questions about this conversion tool and how to use it.
There is no difference — "grammes" is the traditional British English spelling of "grams." Both refer to the same unit of mass in the metric system. The international standard spelling is "gram," but "gramme" is still widely used in British English.
For water: 1 US fluid ounce = 29.5735 grammes, and 1 Imperial fluid ounce = 28.4131 grammes. The exact weight depends on the liquid's density.
The UK uses the metric system for weights, so recipes typically call for grammes rather than ounces. However, older UK recipes may still use Imperial fluid ounces for liquids, making conversion necessary.
For water, multiply the Imperial fluid ounces by 28.4131. For other liquids, multiply by 28.4131 and then by the liquid's specific gravity (density relative to water).
Yes. A UK Imperial fluid ounce is 28.4131 mL, while a US fluid ounce is 29.5735 mL. The Imperial ounce is about 4% smaller.
A UK Imperial pint is 20 Imperial fluid ounces = 568.261 mL = 568.261 grammes of water. This is larger than a US pint (473.176 mL).
