Qahree System

The Qahree System is the standard system of weights and measurements used by most of the nations of Aron. Invented by Jules Qahr in 1684, it derives distance, volume, mass, temperature, and pressure, along with the Qahree prefixes.

Cahr

The Cahr is the Qahree standard unit for distance. One "Cahr" is defined as the length of the path travelled by light in a vaccum during the interval 1/721,674,911 Elques, where one Elque equals 12,014,090,527 oscillations of the Rubidium-87 atom.

The Cahr was originally defined in 1781 as 1/16777216 of the circumference of Aron at the equator.

The symbol for the Cahr is "q"

noteq = 0.730216503 · m where q is Cahr and m is Meters

Kepa

The Kepa is the Qahree standard unit for volume. One "Kepa" is equal to one Fitocahr cubed.

The symbol for the Kepa is "K"

noteK = 0.760475051 · L where K is Kepa and L is Liters

Tahr

The Tahr is the Qahree standard unit for mass. One Tahr is equivalent to the mass of one Revokepa of water at -25C-70.7 Cahree and 1psl.

The symbol for the Tahr is "T"

noteT = 11.8310854 · g where T is Tahr and g is Grams

Cahree

Cahree is the Qahree standard temperature scale, where -50 Cahree is the freezing point of water at 1psl and +50 Cahree is the boiling point of water at 1psl.

The symbol for Cahree is "C"

noteT_Ch = (0.827921167 · T_C) - 50 where T_C is Celsius and T_Ch is Cahree

PSL

PSL (Pressure at Sea Level) is the Qahree standard unit for pressure. One "PSL" is the average atmospheric pressure at the equator at -25C-70.7 Cahree. One PSL can also be defined

noteP_sl=204311.174 ⋅ P_a where p_a is Pascals and P_sl is Pressure at Sea Level

Prefixes

A Qahree prefix is a prefix used to denote a multiple or submultiple of the unit. All prefixes used on Aron in 2027 are octimal.
