The API gravity of a crude oil impacts how many barrels there are per metric ton.
Metric ton = 1,000 kg = 2, 204.6 pounds (avdp)
1 barrel of petroleum = 158.98 liters
barrels of crude oil per metric ton =
= 1 / ((specific gravity) * 0.159)) =
= 6.289 / (specific gravity) =
= (0.0444 * (API gravity)) + 5.84
