Question: 1 liter diesel how much kg?
Answer: 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. kg/litre x litres = kg, kg/m3 x m3 = kg, tonne/m3 x m3 = tonne.
