US and Imperial ounce difference
A US fluid ounce equals 29.5735295625 milliliters. An Imperial fluid ounce equals 28.4130625 milliliters. The same ounce number gives different volumes.
Eight US fluid ounces equal 236.588 milliliters. Eight Imperial fluid ounces equal 227.305 milliliters. Select the standard used by your source.
Fluid ounces measure volume, not ingredient weight. Weight conversion requires the material density. Check package labels before making important decisions.
