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

The smallest unit of time is the tick (t), although it is actually a subdivision of the day (d). One Aarði tick is equal to 4.407852564 of our earth seconds.

  • 1 shake (sh) = 6 ticks
  • 1 hour (h) = 144 shakes
  • 1 watch (w) = 4 hours
  • 1 day (d) = 6 watches
  • 1 moon (m) = 20 days
  • 1 year (y) = 13 moons

Which are related to earth time as follows

  • 1 sh = 26.44711539 seconds
  • 1 h = 3808.384616 seconds (63.47307693 minutes)
  • 1 w = 4.231538462 earth hours
  • 1 d = 25.38923077 earth hours
  • 1 m = 21.15769231 earth days
  • 1 y = 275.05 earth days

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)
