Fluid Ounce (US) (fl oz)
The US fluid ounce, symbol fl oz, measures approximately 29.5735 milliliters. Its origins trace back to the British Imperial fluid ounce but were standardized differently in the United States. It is used for liquids in cooking, beverages, and nutrition. Fluid ounces bridge smaller units, such as teaspoons and tablespoons, with larger units, including cups, pints, and gallons, providing flexibility and precision in culinary measurements.
Liter (L)
The liter (L) is a metric unit of volume, representing 1,000 milliliters. It originated in France as part of the metric system reforms of 1795, initially defined as the volume occupied by one kilogram of water at its densest point. Over time, the liter became a fundamental unit for measuring liquids in science, industry, and everyday life. Its decimal structure makes calculations and conversions straightforward, contributing to its widespread adoption around the world, even as some regions continue to use imperial measures in certain contexts.
