Units

It is not clear whether units should be implemented.

The SI system uses a quantity, a prefix, and a dimension. The first is a number, the second is a letter, an the last is a product of base units

dim Q = L^αM^βT^γI^δΘ^εN^ζJ^η

• L^α – lengde og potens
• M^β – masse og potens
• T^γ – tid og potens
• I^δ – elektrisk strøm og potens
• Θ^ε – termodynamisk trykk og potens
• N^ζ – stoffmengde og potens
• J^η – lysstyrke og potens

Specific sets of base units has their own names, such that Volt (V) is kg·m²·s⁻³·A⁻¹ and that weight is kilogram (kg). The last one is defined with a prefix. Some units can be a bit suprising, such as siemens (S) which is defined as Ω⁻¹ or kg⁻¹⋅m⁻²⋅s³⋅A².
