# Cooking Calculations

### Cooking substance volume <> mass conversions

It's possible to convert between volume and mass if you know the density of the substance involved.

Soulver includes about 200 substances commonly used for cooking.

```
300g butter in cups         | 1.32 cup
10 cups olive oil in grams  | 2,160 g
100g nutella in tablespoons | 5.37 tbsp
```

### Measurement systems

Units of volume have different definitions depending on what country you're in. Soulver supports three systems of measurement:

* US Customary (the default),
* Imperial
* Metric

This setting affects volume units, such as pints, quarts, gallons, teaspoons, tablespoons, and fluid ounces (fl oz).
