1 tsp olive oil in grams
1 tsp of olive oil = 4.5 grams · 4.93 ml · 0.16 oz
That is one teaspoon of olive oil, filled to the rim rather than domed. A full US cup of olive oil weighs 216 g and holds 48 teaspoons, so 1 tsp comes to 4.5 g. Use the converter for any other amount.
Based on a measured density of 216 g per US cup (236.6 ml), poured level rather than to the brim. Last reviewed .
How 1 tsp of olive oil works out
A US teaspoon is 1/48 of a cup, a third of a tablespoon, so take the weight of a cup of olive oil and multiply: 216 × 0.021 = 4.5 g. By volume that is 4.93 ml, the same in the US, UK, Canada and New Zealand.
Australia is the exception: an Australian tablespoon holds 20 ml, not 15, though Australian teaspoons are the same 5 ml as everywhere else. Heaped spoons are not a measure at all; a heaped spoonful can hold half as much again.
Tip: Reserve fruity extra-virgin olive oil for dressings and finishing, where its flavour shows; use lighter refined olive oil for high-heat cooking.
