How many litres of light diesel oil are in a tonne?

PPAC gives 1 tonne of light diesel oil = 1.1720 kilolitres at 29.5 C, or 7.37 barrels. Multiply by 0.9877 for volume at 15 C, about 1,158 litres. Use the mass for CO2, since emission factors for oils are most reliable per kilogram.

The official figures

Steps

  1. Take litres from the invoice and note the temperature basis if printed.
  2. Divide by 1,172 litres per tonne at 29.5 C, or 1,158 at 15 C.
  3. Apply a gas oil factor per kg, since LDO is a distillate close to diesel.

What Senseible does here

Senseible reads the quantity and unit printed on each fuel invoice, converts it with a stated density or calorific value, and shows the factor and source on every line, so a litre or kilogram is never guessed.
