You may, of course, combine conversions as you like. For example, filling your tires with
a maximum pressure of 30 psi the following will help you at a gas station in Europe and
beyond:
resulting in 2.1 bar.
Now you can set the filler and will not blow your tires.
In cases of emergency of a particular kind, remember Becquerel equals Hertz, Gray is
the unit for deposited or absorbed energy (
), and Sievert (Sv) is Gray
times a radiation dependant dose conversion factor for the damage caused in human
bodies.
In this area also some outdated units may be found in older literature: Pour les amis de
Mme. Curie,

. And for those admiring the very
first Nobel laureate in physics, Mr. Röntgen, for finding the x-rays (ruining his hands in
these experiments), the charge generated by radiation in matter was measured by the
unit
. A few decades ago, Rem (i.e. Röntgen equivalent men)
was measuring what Sievert does today.
