Is a UK oz same as US oz?

Answer 1

No.

The UK gallon is not the same as the US gallon and so the fluid ounces are different. With ounce, as a measure of mass, both countries use the avoirdupoise and troy systems so that each has two values of the ounce.

Answer 2

A US fluid ounce and an Imperial fluid ounce are the same. It is the size of an ounce of water by weight.

The confusion occurs with pints, since a US pint is only 16 fluid ounces and a UK pint is 20 ounces. Therefore a US gallon (8 US pints) is only 80% of the size of a UK gallon (8 imperial pints).

This may be one reason, although not the only one, that US cars have the reputation of being such gas guzzlers.
