Antifreeze - Ethylene Glycol Volume vs. Temperature Rating

Freeze protecting of cooling systems - temperature rating vs. required amount of antifreeze.

Required amount of antifreeze to protect cooling systems at specific temperature ratings can be estimated from the charts below:

Cooling system - protection temperature and required amount of antifreeze

t_C = 0.56 (t_F - 32) = 5/9 (t_F - 32)
1 Gallon (U.S.) = 3.785x10^-3 m³ = 3.785 dm³ (liter) = 231 in³ = 0.13368 ft³ = 4.951x10^-3 yd³ = 0.8327 Imp. gal (UK) = 4 Quarts = 8 Pints

Never use more than 70% antifreeze in a cooling system.
