Cups and milliliters in recipes
The cup is a unit for measuring volume with several definitions in use. The most used is the US legal cup which is defined as containing 240 ml of volume as per a 1970 international treaty the US is a part of. Pre-1970 American recipes might contain measurements in Imperial cups which are slightly larger at 284 ml. Both of these are supported by this converter.
Milliliters are a well defined unit as one thousand part of the liter (a.k.a. litre), the base unit of the international measurement system, also known as the metric system. The cup is in fact defined in terms of milliliters which makes conversions between the two units straightforward as they also measure the same thing: volume.
