JET-A density vs temperature

[tesh76]

Is there a useable formula to correlate temperature to fuel density particularly Jet-A ? I am aware of the Coefficient of Thermal Expansion value of 999 x 10E-6 (ie .00099) per Deg C but reluctant to use this as there may be other variables to consider... Trying to plan airplane fuel requirements in gallons since most flight planning systems work in pounds.

ASTM D 1655 shows Density at 15 deg C, kg/m3 as 775 to 840 for Jet A or Jet A-1.

There is a spreadsheet at

Unless anyone can advise any specific constants to use other than the default values then I think this will suit but you'll need to convert from kg/m3 to whatever alternative you need.
