Frequently Asked

How many cups are in a liter?: There are 4.227 US legal cups in 1 liter. For quick kitchen measurements, round this to 4.2 cups. Note that metric cups used in Australia, New Zealand, and parts of Europe are exactly 250 ml, which means exactly 4 metric cups fit in a liter.
How many grams are in an ounce?: 1 dry ounce is exactly 28.3495 grams. When baking, most cooks round this to 28 grams for convenience. Be careful not to confuse dry ounces (weight) with fluid ounces (volume), which measure space rather than mass. Source: Wikipedia
How many centimeters in an inch?: 1 inch is exactly 2.54 centimeters. This is an internationally standardized value since 1959. To quickly estimate, you can think of one inch as roughly the width of a standard adult thumb. Source: NIST Guide to SI
