When I first started living and cooking in America, I had two prevailing thoughts about US measurements:

1) How many ounces in a pound? How many ounces in a quart? Wait – are the ounces different?!

2) A pound is a smidge under 454 grams? You’ve got to be joking – why can’t it simply be half a kilo? Why not just use metric units? 

These days, I’m only slightly less confused, so I keep this quick-and-dirty guide on hand for common conversions.

Spoons and cups | Volume measurements

NB: In baking, weight measures are preferred over volume measures for dry ingredients. A digital food scale is fairly affordable, and often includes a tare function, which means ingredients can be added straight into the mixing bowl. This also means less washing-up… yasss.

The measurements below are rounded up to the nearest whole number:

Australian US
Teaspoon 5mL 5mL
Tablespoon 20mL* 15mL
Cup 250mL 237mL

240mL (nutrition labelling purposes)

* 20mL is the “Australian standard” tablespoon

Weight measurements
