Not necessarily. I buy oil in litres.
Specific Gravity probably depends on Manufacturer, I found 0,885 g/cm³ wich leads to: (1 kg)/(0,885 kg/L) = 1,13 L
Depends on what substance. A litre of water weighs 1 kg, 70 kg of water is 70 litres. For other liquids you have to go into the realm of Specific Gravity, which is the ratio of the weight of equal volumes of the liquid and water.
For standard water under standard conditions ... 1 liter of water has 1 kilogram of mass ===> 250 liters has 250 kg of mass. On the surface of the earth, 1 kg weighs 2.20462 pounds ===> 250 kg weighs (250 x 2.20462) = 551.155 pounds
The unit of measure here would probably be l, for liters.
One liter weighs 1000 grams (1 Kg) 2 liters is twice that.
1
3 liters of water or any other substance with the same density of water.
It is 0.95 Kg
20 liters of water (at sea level)
10 liters = 10 kg (22.05 lbs) of water, since water has a density of 1kg/L.
729 kg
Assuming you mean "How many kilos of water in 90 liters?", the answer is 90 kg.
1 kg water = 1 litre
1 kg of water is equal to 1 litre
That weighs 25 kg.
1 liter of water weighs 1 kg
One liter of water is almost exactly one kilogram.
