The degree Celsius is the unit of temperature on the Celsius scale,
one of two temperature scales used in the
International System of Units (SI), the other being the Kelvin scale.
A degree (in full, a degree of arc, arc degree, or arcdegree),
usually denoted by ° (the degree symbol), is a measurement
of a plane angle in which one full rotation is 360 degrees
The Delisle scale is a temperature scale,
notable as one of the only temperature scales that is
inverted from the amount of thermal energy it measures.
Fahrenheit temperature scale,
based on 32° for the freezing point of water
and 212° for the boiling point of water,
the interval between the two being divided into 180 equal parts.
The inch (symbol: in or ″) is a unit of length
in the British imperial and the United States
customary systems of measurement.
It is equal to 1/36 yard or 1/12 of a foot.
The Rankine scale is an absolute
scale of thermodynamic temperature.
Zero on the Rankine scale is absolute zero,
but a temperature difference of one Rankine degree
is defined as equal to one Fahrenheit degree,
rather than the Celsius degree used on the Kelvin scale.
The Réaumur scale, also known as the "octogesimal division",
is a temperature scale for which the melting and boiling points
of water are defined as 0 and 80 degrees respectively.
The Rømer scale also known as Romer or Roemer,
is a temperature scale, based on the freezing point
of pure water being 7.5 degrees and the boiling point
of water as 60 degrees.
