1 spoon =15ml

or

1 spoon =20ml, there are two standards for measurement in mainstream western countries, and a good recipe will tell you which one it uses. If not specified, it is usually 15ml.

A teaspoon is lighter than a spoon. Generally speaking, a teaspoon refers to a small iron spoon, which is relatively flat and can only hold a little liquid. Spoon refers to a spoon made of ceramics, which is deep and can hold more liquid. According to my experience, the ratio of teaspoon to spoon in the recipe is about 4: 1, which means that four teaspoons are equal to one spoon.
