How Much Is 340 Milliliters of Water in Ounces?
340 milliliters of water weighs 11.99 oz. This is based on water having a density of 236.59g per cup. Because milliliters measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 340 milliliters.
Formula and Step-by-Step
- Start with 340 milliliters of water
- 1 milliliter of water = 1g
- 340 × 1 = 340.00g
- Convert grams to ounces: 340.00 ÷ 28.3495 = 11.99 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

Understanding the Units
What is a Milliliter?
A milliliter (ml) is a metric unit of volume equal to 1/1000 of a liter. It is the standard volume measurement for cooking in most countries outside the US. One cup equals approximately 236.588 milliliters.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
