The system of measurement used in Aarð is closer to *our* US/Imperial system than metric. It was based on early measurement using one's body, and was standardized by the Ðanmar Empire.

Linear Measure

The basic unit of linear measure is the standard inch (si), equivalent to about 1.27 of *our* inches or 3.2258 cm.

  • 1 standard foot (sf) = 8 si
  • 1 hand (h) = 5 si
  • 1 walk (wk) = 144 sf
  • 1 standard league (sl) = 24 wk (3456 sf)
  • 1 great league (gl) = 6 sl (144 wk or 20736 sf)

These are related to metric and the US system as follows:

  • 1 sf = 25.8064 cm (10.16 in)
  • 1 h = 16.129 cm (6.35 in)
  • 1 wk = 37.161216 m (121.92 ft)
  • 1 sl = 891.869184 m (2926.04 ft or 0.554 mi)
  • 1 gl = 5.351215204 km (3.325 mi)

US equivalents are approximate; metric equivalents are closer to the actual values.

Time Measure

Aarði time measurement is based on subdivisions of the 23.37819831 hour Aarði day.

  • 1 tick = 4.058714984 seconds
  • 1 moment = 6 ticks (24.35228991 seconds)
  • 1 hour = 144 moments (58 minutes 26.7297465 seconds)
  • 1 watch = 4 hours (3 hours 53 minutes 8.61942 seconds)
  • 1 day = 6 watches (23 hours 22 minutes 41.5190768 seconds)
  • 1 moon = 20 days (19 days 11 hours 33 minutes 50.27815411 seconds)
  • 1 year = 13 moons (253 days 6 hours 19 minutes 53.778 seconds)

Measure of Weight

The basic unit of weight is the grain (gr).

  • 1 pebbleweight (pw) = 24 grains
  • 1 standard pound (sp) = 12 pebbleweights
  • 1 haul (hl) = 144 standard pounds
  • 1 ton (not abbreviated) = 144 hauls (20,736 sp)
  • 1 long ton (lt) = 72 tons (1,492,992 sp)
