The ancient Greeks and Romans also developed their own systems, with the “kyathos” and “cyathus” being used to measure liquids.
The modern system of liquid measurements, however, is based on the metric system, which was introduced in the late 18th century. The metric system provides a standardized and logical framework for measuring volumes, with the liter being the base unit. The milliliter, as a subdivision of the liter, has become a widely accepted unit of measurement for small volumes of liquids.
Conversion Factors
To convert between ounces and milliliters, it’s necessary to understand the conversion factors. One fluid ounce is equal to approximately 29.6 milliliters. This means that if you have a recipe that calls for 1 oz of a liquid ingredient, you can substitute it with approximately 29.6 mL. However, it’s essential to note that this conversion is not exact, as the density of the liquid can affect the volume.
For example, 1 oz of water is equal to 29.6 mL, but 1 oz of honey is equal to approximately 28.4 mL, due to the difference in density. Therefore, it’s crucial to consider the type of liquid being measured when converting between ounces and milliliters.
