State the planning density
The worksheet uses the app’s planning assumptions of 6.0 lb per US gallon for avgas and 6.7 lb per US gallon for Jet-A. It converts between US gallons, litres, pounds and kilograms using the selected assumption.
Actual fuel density varies with temperature and composition. A correctly calculated planning conversion is not a temperature-corrected measurement. Check the applicable aircraft documents and measured information when the value affects loading or operation.
Read the assumption with the result
The result includes the density used and identifies it as a planning assumption. Keep that context with a copied or exported number; a mass value without its source density can be misleading.
