There is no equivalence.

A pound is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a litre of air. How many pounds? Next consider a litre of water. How many pounds?

The masses of equal volumes of the two substances will clearly be very different.

There is no direct conversion between mass and volume:

**You need to know the density of the substance to enable
you to carry out the conversion**.

If you can find the density of the substance (grams) then to convert the amount of litres to pounds:

- Convert it to kilograms to maintain the same unit
- Multiply the number of kilograms by 2.20462 (pounds/ kilogram)
- The result will be the amount of litres of the substance in kilograms
