>>8758937Sometimes metric is more useful, sometimes imperial. Inches are generally better for things you can hold with one hand. Cm is generally too precise, so likely to be rounded to 5s, whereas guessing things to an inch is about right. A pint is a reasonable measurement for a drink, but a gallon is a lot for a container, so I think even Americans will say 2 litres. Fahrenheit seems excessively precise for temperature.
