How Much Is 1 Milliliter of Water in Ounces?

Converting 1 milliliter of water to ounces gives 0.04 oz. One milliliter of water weighs 1g (0.04 oz). This conversion is specific to water because each ingredient has a different density.

1 milliliter of water is also
0.04

Formula and Step-by-Step

milliliters × 1g/ml ÷ 28.3495g/oz = ounces
  1. Start with 1 milliliter of water
  2. 1 milliliter of water = 1g
  3. 1 × 1 = 1g
  4. Convert grams to ounces: 1 ÷ 28.3495 = 0.04 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

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?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 0.04 oz, based on water having a density of 236.59g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of milliliters by 1 (grams per milliliter for water), then divide by 28.3495 to convert grams to ounces. For 1 milliliter: 1 × 1 = 1g, then 1 ÷ 28.3495 = 0.04 oz.
For the most accurate results, weigh water on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of water changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 0.04 oz × 28.3495 = 1g, then 1g ÷ 1 = 1 milliliter. Or use the Ounces to Milliliters converter.
