A biofuel that when mass-produced costs only 105% as the energy equivalent of gasoline.

We first need the energy equivalent of one atomic mass unit:

Particle physicists measure mass in terms of its energy equivalent, because the units are more practical.

The energy equivalent is less than 1.5 gallons of gasoline.

An old tire contains the energy equivalent of 2.5 gallons of oil.

The energy equivalent of rest mass m is mc.

Suppose we applied a really high tax, $1, on the energy equivalent of a gallon of gasoline.

They can be seen from so far away because they shine with an energy equivalent to billions of suns.

An average hurricane disperses the energy equivalent of about 10 000 atom bombs.

The watt-second is the energy equivalent to the power of one watt sustained for one second.
