Question: 1 liter diesel is equal to how many kg?
Answer: It depends on the density/specific gravity of the fuel. Diesel for automotive use is around 832kg/m3, or 0.832kg/litre, so there you go - 832g. It's quite easy really - 1 m3 of water has a mass of 1000kg, or 1tonne per m3. One m3 of diesel has a mass of 832kg.
