Kilograms of plain yogurt to litres runs on one number, 0.96566627 litres per kilogram. 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.
Water is the yardstick: 1 mL of it weighs 1 g. Plain yogurt 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.
A litre of plain yogurt weighs 1.0356 kg, because its density is 1.0356 kg per litre. Litres and kilograms are the units this ingredient is actually bought in at any scale beyond a single recipe, which is what makes this the useful conversion for batch cooking and for costing.
A kilogram of plain yogurt is 4.082 cups, and a 500 g pack is 2.041 cups. Metric pack sizes are round numbers in weight and awkward ones in volume, which is the practical argument for scaling a recipe by weight: 2.041 cups is a measurement you have to count out, 500 g is one you read off.
How the figure is arrived at: Plain and unstrained. Greek yogurt is much thicker but only slightly heavier per cup.
The formula
kilograms- The amount of plain yogurt you are converting, in kilograms
0.965666271429- Litres per kilogram for plain yogurt, from its density of 1.0356 g/mL
litres- The equivalent quantity in litres
How it works, step by step
- Enter the quantity in kilograms.
- It is multiplied by 0.965666271429, the litres-per-kilogram figure for plain yogurt.
- The result appears in litres, with a second reading in cups beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
1/2 kg of plain yogurt in litres
1/2 kg of plain yogurt weighs out at 0.482833 litres. Divide 0.482833 by 0.96566627 and you get back to 1/2 kg, which is the quickest check that the factor is the right way up.
1 kg of plain yogurt in litres
A recipe calling for 1 kg of plain yogurt needs 0.965666 litres on the scale. The arithmetic is 1 × 0.96566627 = 0.96566627, and halving the recipe halves the weight to 0.482833 litres.
2 kg of plain yogurt in litres
A recipe calling for 2 kg of plain yogurt needs 1.93133 litres on the scale. The arithmetic is 2 × 0.96566627 = 1.9313325, and halving the recipe halves the weight to 0.965666 litres.

Frequently asked questions
How many litres are in 1 kg of plain yogurt?
One kilogram of plain yogurt is 0.96566627 litres. Half that quantity is 0.482833 litres and double it is 1.93133 litres, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of plain yogurt not 236 g like water?
Because weight per cup depends on what is in the cup. Plain yogurt 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. Plain yogurt 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 plain yogurt 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 plain yogurt 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 plain yogurt 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?
A scale, if the result matters. Volume measuring carries a spread of about 1% for plain yogurt — roughly 2.45 g on a 245 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 L of plain yogurt weigh?
2 L of plain yogurt comes to 2071.1 g, or 2.0711 kilograms. This page runs that calculation in reverse — enter a weight and it returns the volume — and the liters-to-kg page does it in the direction the question is usually asked.
