At what temperature should the fuel gravity be taken?

Fuel gravity varies with temperature because liquids expand when warm and contract when cold. To compare readings reliably, a standard reference temperature is used. For fuel gravity, that standard is 60°F. Measuring at this temperature lets you reference established correction tables and compare readings consistently across tanks and times. If you measured at higher temperatures like 75°F, 90°F, or 120°F, the fuel would be less dense than its 60°F value, and you’d need to apply corrections to convert to the 60°F basis. So the correct practice is to take the fuel gravity at 60°F.
