Hello and welcome to Just Answer!

There are two types of jet fuel used in commercial aviation: Jet A (and its version Jet A-1) and Jet B. They have slightly different densities. Jet A / Jet A-1 is the most common type.

According to Chevron, at 15 ºC the densities are

Jet A / Jet A-1: 0.775 to 0.840 kg/L
Jet B: 0.751 to 0.802 kg/L

So, 1 liter of jet fuel can weigh between 0.75 and 0.84 kg. If you need one specific number, you can use 0.81 kg, which is roughly the average for Jet A / Jet A-1 type.

Let me know if you need more help with this question.
