Kilograms to Liters: Does 1 kg Equal 1 Liter?
Only water (and liquids with the same density) converts one to one. Honey and syrup are heavier; oil and flour are lighter.
Kilograms measure weight and liters measure volume, so converting between them needs the ingredient's density. Water weighs almost exactly 1 kg per liter. Oils are lighter, so 1 kg of olive oil takes up more than a liter, while honey is much denser and 1 kg fits in about ¾ liter.

| Ingredient | ½ kg | 1 kg |
|---|---|---|
| Water | 0.499 liter | 0.998 liter |
| Milk | 0.485 liter | 0.97 liter |
| Olive oil | 0.548 liter | 1.1 liters |
| Honey | 0.348 liter | 0.696 liter |

Weight of 1 liter in kg
| Ingredient | 1 liter |
|---|---|
| Water | 1 kg |
| Milk | 1.03 kg |
| Olive oil | 0.913 kg |
| Honey | 1.44 kg |
| Maple syrup | 1.36 kg |
Weights and volumes on this page use these grams-per-US-cup densities: water 237 g; milk 244 g; olive oil 216 g; honey 340 g; maple syrup 322 g; all-purpose flour 125 g; granulated sugar 200 g. Packing, sifting and brand can shift real results by 5–15%, so weigh when a recipe depends on precision.
