To convert grams of skim milk into millilitres, multiply by 0.96566627: one gram comes to 0.96566627 millilitres. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Water is the yardstick: 1 mL of it weighs 1 g. Skim milk comes in at 1.0356 g per mL, or 103.6% of water, which is why a cup of it is 245 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
Skim milk has a density of 1.0356 g per mL, so 100 mL of it weighs 103.6 g and 250 mL weighs 258.9 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 103.6% as heavy as the same volume of water.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.408% of a cup of skim milk, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.041 cups, and a 1 kg pack 4.082.
How the figure is arrived at: Marginally denser than whole milk, because the fat removed from it was the lightest part.
The formula
grams- The amount of skim milk you are converting, in grams
0.965666271429- Millilitres per gram for skim milk, from its density of 1.0356 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.965666271429, the millilitres-per-gram figure for skim milk.
- The result appears in millilitres, with a second reading in tsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of skim milk in millilitres
Take 50 g of skim milk: 50 × 0.96566627 gives 48.2833 millilitres. Doubling the batch takes it to 96.5666 millilitres, because the relationship is a straight proportion once the density is known.
150 g of skim milk in millilitres
Take 150 g of skim milk: 150 × 0.96566627 gives 144.85 millilitres. Doubling the batch takes it to 289.7 millilitres, because the relationship is a straight proportion once the density is known.
500 g of skim milk in millilitres
A recipe calling for 500 g of skim milk needs 482.833 millilitres on the scale. The arithmetic is 500 × 0.96566627 = 482.83314, and halving the recipe halves the weight to 241.417 millilitres.

Frequently asked questions
How many millilitres are in 1 g of skim milk?
One gram of skim milk is 0.96566627 millilitres. Half that quantity is 0.482833 millilitres and double it is 1.93133 millilitres, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of skim milk not 236 g like water?
Because weight per cup depends on what is in the cup. Skim milk has a density of 1.0356 g per mL where water has 1.00, so a cup of it weighs 245 g rather than 236.6 g. That is a difference of 8.4 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Barely. Skim milk does not compress, so a cup of it is 245 g however it is poured — within about 1%, which is inside the accuracy of a domestic scale. This is the group where measuring by volume is defensible.
Is a fluid ounce of skim milk the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of skim milk weighs 1.08 oz, so the two readings differ by 8.03%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of skim milk would weigh 258.89 g instead of 245 g — 13.9 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One millilitre of skim milk is 1.036 g, and a scale reading to the nearest gram is working at 96.6% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How much does 15 mL of skim milk weigh?
15 mL of skim milk comes to 15.533 g, or 15.533 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the ml-to-grams page does it in the direction the question is usually asked.
