Density tools
- Metric tonne ethanol = 7.94 petroleum barrels = 1262 liters
- ethanol energy content (LHV) = 11,500 Btu/lb = 75,700 Btu/gallon = 26.7 GJ/t = 21.1 MJ/liter. HHV for ethanol = 84,000 Btu/gallon = 89 MJ/gallon = 23.4 MJ/liter
- ethanol density (average) = 0.79 g/ml ( = metric tonnes/m3)
- Metric tonne biodiesel = 37.8 GJ (33.3 - 35.7 MJ/liter)
- biodiesel density (average) = 0.88 g/ml ( = metric tonnes/m3)

Density and conversion factors useful for international trade
In Europe we use to trade FAME (biodiesel) and vegetable oil in ton, Ethanol is trade in Gallons or Liter.

Areas and crop yields
- 1.0 hectare = 10,000 m2 (an area 100 m x 100 m, or 328 x 328 ft) = 2.47 acres
- 1.0 km2 = 100 hectares = 247 acres
- 1.0 acre = 0.405 hectares
- 1.0 US ton/acre = 2.24 t/ha
- 1 metric tonne/hectare = 0.446 ton/acre
- 100 g/m2 = 1.0 tonne/hectare = 892 lb/acre
