How many barrels of crude oil in one MT? . by Robert Fogt on 07/14/03 at 21:27:32 
Petroleum has a specific gravity of 0.88
which means 
1 liter weighs 0.88 kilograms. 
From the volume page we know that: 
 1 barrel [US, petroleum] = 158.9872972 liter 
So 1 barrel weighs: 158.9872972 * 0.88 = 139.908821536 kilograms 
1 metric ton is 1000 kilograms: 
kg 139.908821536 / 1000 = 7.1475121 barrels 
Barrel 7.1475121 = 1 metric ton
correct specific gravity 0.88

1.3 million barrels  =   tons 206'683.486
this amount of bunkered oil has been reported caught by Nigerias Minister of Finance and Economy coordination
