LPG around the world includes mixes of Propane and Butane. Propane has a low boiling point so it is more suited for colder environments. It evaporates at -42°C at atmospheric pressure. Butane doesn't burn well at lower temperatures, it evaporates at around 0°C at atmospheric pressure.

The LPG grades are defined by the temperature at which they reach the minimum pressure of 150 kPa.
| LPG grades | Temperature | Possible Propane/Butane mixtures |
|---|---|---|
| grade A | -10°C | from 100%/0% to 60%/40% |
| grade B | -5°C | from 60%/40% to 40%/60% |
| grade C | 0°C | from 40%/60% to 30%/70% |
| grade D | +10°C | from 30%/70% to 10%/90% |
| grade E | +20°C | from 10%/90% to 0%/100% |
