Grams of sweetened condensed milk to cups runs on one number, 0.0032679739 cups per gram. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
Put next to water — 1 g per mL exactly — sweetened condensed milk measures 1.2934 g per mL. That ratio, 129.3%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A cup of sweetened condensed milk is 306 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 304.5 g and 309.1 g covers the range from lightly spooned to firmly packed. That 1% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
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
grams- The amount of sweetened condensed milk you are converting, in grams
0.00326797385621- Cups per gram for sweetened condensed milk, from its density of 1.2934 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.00326797385621, the cups-per-gram figure for sweetened condensed milk.
- The result appears in cups, with a second reading in tbsp 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 sweetened condensed milk in cups
Take 50 g of sweetened condensed milk: 50 × 0.0032679739 gives 0.163399 cups. Doubling the batch takes it to 0.326797 cups, because the relationship is a straight proportion once the density is known.
150 g of sweetened condensed milk in cups
150 g of sweetened condensed milk weighs out at 0.490196 cups. Divide 0.490196 by 0.0032679739 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of sweetened condensed milk in cups
500 g of sweetened condensed milk weighs out at 1.63399 cups. Divide 1.63399 by 0.0032679739 and you get back to 500 g, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many cups are in 1 g of sweetened condensed milk?
One gram of sweetened condensed milk is 0.0032679739 cups. Half that quantity is 0.00163399 cups and double it is 0.00653595 cups, 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?
A scale, if the result matters. Volume measuring carries a spread of about 1% for sweetened condensed milk — roughly 3.06 g on a 306 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How much does 2 cup of sweetened condensed milk weigh?
2 cup of sweetened condensed milk comes to 612 g, or 612 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the cups-to-grams page does it in the direction the question is usually asked.
