How do I convert cups to milliliters?

How do I convert liters to cubic meters?

Divide the number of liters by 1,000 to get cubic meters, since 1 cubic meter equals exactly 1,000 liters. This conversion is common in construction, shipping, and industrial contexts that measure large volumes.

What is the difference between a US and UK gallon?

A US gallon equals about 3.785 liters, while a UK (imperial) gallon equals about 4.546 liters — roughly 20% larger. This difference also applies to pints, quarts, and fluid ounces, so recipes and fuel economy figures can differ significantly between the two systems.
