How much gas does a 747 jet airliner use to take off?
user
Hm, it really depends on the runway length and air density. I’d estimate something around 800 gallons per take-off, but for more accurate estimates I need to know some more about the runway length and air density, such as by knowing the runway length in meters and air density in kilograms per cubic meter.

Wow! That is a lot of fuel!
user
Yes, airplanes and most ships use a lot of fuel to take off.

Really!  Are you trying to calculate the whole world’s carbon footprint?
