Everything you need to know about measuring and converting metric milliliters to fluid ounces, from terms and origin to how many milliliters are in an ounce, and other helpful measurements.
How Many ml In An Oz
There are 29.573 milliliters in a fluid ounce.
Milliliters are a metric unit of measurement, while ounces are an Imperial measurement (difference between metric and Imperial here).
The United States is only one of three nations still using the Imperial Measurement system and ounces, the other two are Liberia and Myanmar. With this in mind, the conversion of ounces into the metric volume measurement of milliliters is becoming increasingly important, with so many recipes now use metric measurements.
What Is an Ounce?
Ounces comes from the Roman term “uncia.” The uncia was 1/12 of a Roman copper bar used as a tool to measure the length of an inch and the weight of an ounce. The Romans had no fluid ounce volume measurement. For that we had to wait on England. Modern ounce weight and volume measurements both come from Britain. A dry ounce weighs 1/16 of a pound, or 28.35 grams. A fluid ounce is the amount of water that weighs one ounce. A fluid ounce is also 1/16th of a pint.
What Is a Milliliter?
The liter was introduced in France in 1795 by the revolutionary government after overthrowing the monarchy and everything associated with it, and so the world in time got the metric system. In 1901 an international agreement defined the liter as the space occupied by 1 kg of pure water. A milliliter was then defined as 1/1,000th of a liter or the volume of one gram of pure water.
