metric tons to gallons

trying to figure out the conversion of 1 metric ton to U.S. gallons (gasoline)...


does it work to simply convert a metric ton (2200 lbs ?) to gallons figuring 8 lbs/gallon (? I'm not sure of fuel weight/gal.) or is there some kind of volume component?

thanks,
tc

The density of fuel varies a little between lots and refineries, so it is good to have a measured value. But gasoline runs about 0.74 kg/L, so 1 t = 1000 kg and
1000 kg x 1 L/0.74 kg = 1351 L

1 US gallon = 3.7854 L, so about 357 gallons.

Rework it with density of 0.73 and 0.75, gasoline can vary that much or more, and you'll see why you need a measured desnntiy for a specific lot of fuel.

fyi this relates to cruise ships: 80 to 100,000 ton ship uses 195 M tons of fuel/ day so 69,615 gallons ! a 5 day cruise= 348,075 gallons! say they cruise 50 weeks/ year = 17 Million Four Hundred thousand gallons on a freekin floating hotel !

They don't use gasoline. They use heavy heating oils and residual oils, generally heavier than diesel (0.85 kg/L), typically around 0.9 kg/L and higher.

But there was another thread here, in which I determined that per passenger mile, their fuel economy is worse than a 747 (they are much slower, and require much more space and weight per passenger). But airlines get bad press on fuel economy and emissions, no one says anything about cruise ships.
