AvGas weight

[pmulcahy11b]

At one point, either on this board or its predecessor, we had a discussion about fuel weight. I can't find the thread now, and I need to know the weight of AvGas, either by gallon or liter. Can anyone help here?

Can't say as to JP8, but Aviation Grade A is .82KG per Litre. From what I understand, JP8 is pretty close to A, so I would go anywhere between .8 to .82 a Litre.

All grades of avgas that meet CAN 2-3, 25-M82 have a density of 6.01 lb/U.S. gal at 15 °C, or 0.721 kg/l, and this density is commonly used for weight and balance computation. Density increases to 6.41 lb/US gallon at -40 °C, and decreases by about 0.5% per 5 °C (9 °F) increase in temperature
