Why are US and UK gallons different?

The US kept the Queen Anne wine gallon (231 cubic inches) while the UK redefined the gallon in 1824 to be exactly 10 pounds of water.

What's the difference between a US and metric cup?

A US cup is 236.6ml while a metric cup (used in Australia, Canada) is exactly 250ml — about 5.7% larger.

How many tablespoons in a cup?

16 US tablespoons = 1 US cup. In Australia, it's 12.5 tablespoons because Australian tablespoons are larger (20ml vs 15ml).
