Crude petroleum, and the refined products made from crude oil, are normally measured either by volume in gallons and US barrels, or by weight in tons or tonnes. The relationship between volume and weight is usually measured by density in the United Kingdom (the alternative measure is relative density or specific gravity). American oilmen usually reckon
quantities of oil produced, moved or processed in barrels per day (bpd or b/d). The loose but simple rule of thumb for conversion is that a barrel a day is roughly 50 tonnes a year, but the relationship varies according to density and so according to product.

The ton of oil equivalent (toe) is a unit of energy: the amount of energy released by burning one metric ton of crude oil, approximately 10 Gcalth or 42 GJ (as different crude oils have different calorific values, the exact value of the toe is defined by convention; unfortunately there are several slightly different definitions as discussed below).

The toe is commonly used for large amounts of energy, as it is more intuitive to visualise, say, the energy released by burning 1000 number of tonnes of oil than 42,000 billion joules (the SI unit of energy).

A barrel of oil equivalent (boe), also a unit of energy, contains approximately 0.146 toe (i.e. there are approximately 6.841 boe in a toe).

Multiples of the toe are used, in particular the megatoe (Mtoe, one million toe) and the gigatoe (Gtoe, one billion toe).

The IEA/OECD define one toe to be 10 Gcalth, equal to 41.868 GJ [1] or 11.625 MWh.

Some organisations use other conversion factors, for example:

One toe = 42 GJ
one toe = 41.85 GJ[2]
One toe = 7.11, 7.33, or 7.4 boe
One ton petroleum equivalent (TPE), a parameter used in renewable energy, 10,800,000,000 calIT (45.217 gigajoules).

Petroleum has a specific gravity of 0.88 kg/lit

1 bbl ~ 159 liter and a metric ton (MT) is 1000 kg

159 lit/bbl * 0.88 kg/lit * MT/1000 kg = 0.14 MT/kg

Therefore there are ~ 7.14 barrels per metric ton

Nope! It on no account works that way. gas fees is going up on the slightest hint of any oil will boost, real or fake. notwithstanding it takes weeks for that to mirror on the pumps, if in any respect.
