One millilitre of sweetened condensed milk is 1.2933864 grams, so converting millilitres of sweetened condensed milk to grams means multiplying by 1.2933864. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
The density behind that figure is 1.2934 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of sweetened condensed milk weighs 306 g, so this ingredient is 129.3% as heavy as the same volume of water — the single fact the whole page rests on.
Sweetened condensed milk has a density of 1.2934 g per mL, so 100 mL of it weighs 129.3 g and 250 mL weighs 323.3 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 129.3% 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 0.327% of a cup of sweetened condensed milk, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 1.634 cups, and a 1 kg pack 3.268.
How the figure is arrived at: The added sugar makes it the densest dairy liquid in a normal kitchen, and sticky enough that scraping the cup out matters.
The formula
millilitres- The amount of sweetened condensed milk you are converting, in millilitres
1.29338636835- Grams per millilitre for sweetened condensed milk, from its density of 1.2934 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in millilitres.
- It is multiplied by 1.29338636835, the grams-per-millilitre figure for sweetened condensed milk.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
15 mL of sweetened condensed milk in grams
15 mL of sweetened condensed milk weighs out at 19.4008 grams. Divide 19.4008 by 1.2933864 and you get back to 15 mL, which is the quickest check that the factor is the right way up.
100 mL of sweetened condensed milk in grams
A recipe calling for 100 mL of sweetened condensed milk needs 129.339 grams on the scale. The arithmetic is 100 × 1.2933864 = 129.33864, and halving the recipe halves the weight to 64.6693 grams.
250 mL of sweetened condensed milk in grams
250 mL of sweetened condensed milk weighs out at 323.347 grams. Divide 323.347 by 1.2933864 and you get back to 250 mL, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many grams are in 1 mL of sweetened condensed milk?
One millilitre of sweetened condensed milk is 1.2933864 grams. Half that quantity is 0.646693 grams and double it is 2.58677 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of sweetened condensed milk not 236 g like water?
Because weight per cup depends on what is in the cup. Sweetened condensed milk has a density of 1.2934 g per mL where water has 1.00, so a cup of it weighs 306 g rather than 236.6 g. That is a difference of 69.4 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. Sweetened condensed milk does not compress, so a cup of it is 306 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 sweetened condensed 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 sweetened condensed milk weighs 1.349 oz, so the two readings differ by 34.9%. 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 sweetened condensed milk would weigh 323.35 g instead of 306 g — 17.3 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 sweetened condensed milk is 1.293 g, and a scale reading to the nearest gram is working at 77.3% 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 many millilitres of sweetened condensed milk is 500 g?
500 g of sweetened condensed milk is 386.58 millilitres — 0.773164 millilitres to one gram, so 500 × 0.773164 = 386.58. Going that way is a division by 1.29339, or a multiplication by 0.773164 if you prefer.
