One litre of plain yogurt is 1.0355544 kilograms, so converting litres of plain yogurt to kilograms means multiplying by 1.0355544. 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 1.0356 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of plain yogurt weighs 245 g, so this ingredient is 103.6% as heavy as the same volume of water — the single fact the whole page rests on.
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.
What the number depends on: Plain and unstrained. Greek yogurt is much thicker but only slightly heavier per cup.
The formula
litres- The amount of plain yogurt you are converting, in litres
1.03555444524- Kilograms per litre for plain yogurt, from its density of 1.0356 g/mL
kilograms- The equivalent quantity in kilograms
How it works, step by step
- Enter the quantity in litres.
- It is multiplied by 1.03555444524, the kilograms-per-litre figure for plain yogurt.
- The result appears in kilograms, with a second reading in lb beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
1/2 L of plain yogurt in kilograms
Take 1/2 L of plain yogurt: 0.5 × 1.0355544 gives 0.517777 kilograms. Doubling the batch takes it to 1.03555 kilograms, because the relationship is a straight proportion once the density is known.
1 L of plain yogurt in kilograms
Take 1 L of plain yogurt: 1 × 1.0355544 gives 1.03555 kilograms. Doubling the batch takes it to 2.07111 kilograms, because the relationship is a straight proportion once the density is known.
2 L of plain yogurt in kilograms
Take 2 L of plain yogurt: 2 × 1.0355544 gives 2.07111 kilograms. Doubling the batch takes it to 4.14222 kilograms, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many kilograms are in 1 L of plain yogurt?
One litre of plain yogurt is 1.0355544 kilograms. Half that quantity is 0.517777 kilograms and double it is 2.07111 kilograms, 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 many litres of plain yogurt is 1 kg?
1 kg of plain yogurt is 0.96567 litres — 0.965666 litres to one kilogram, so 1 × 0.965666 = 0.96567. Going that way is a division by 1.03555, or a multiplication by 0.965666 if you prefer.
