Units Fields

The specification for Units has these fields:

unit

Optional-string
human readable unit symbol, here N for Newton

N
exponent

Optional-number[]
7-tuple of integer-valued exponents*- Ordered list of SI base units

  • 1st entry: Length - meter (m)
  • 2nd entry: Time - second (s)
  • 3rd entry: Amount of substance - mole (mol)
  • 4th entry: Electric current - ampere (A)
  • 5th entry: Temperature - kelvin (K)
  • 6th entry: Luminous intensity - candela (cd)
  • 7th entry: Mass - kilogram (kg)

Explanation

the exponents reference the above SI base units in the corresponding order to describe the unit w.r.t. the base SI units, the entries [1, -2, 0, 0, 0, 0, 1] thus denote m s⁻² kg, i.e., Newton

[1, -2, 0, 0, 0, 0, 1]
offset

Warning

For absolute temperatures only! For temperature differences, this must be omitted!

scale

Optional-number
default value is 1*- allows to scale the values into base units, e.g., 1e-3 to describe mm (millimeters) in terms of m (meters)
