The unit of length is the pada (symbol pad), defined as the path travelled by light in a vacuum during a time interval of ¹⁄_{1352,5510,4032} ¹⁄_599,584,916 of an agrima.

From the pada and the agrima, we define the following coherent derived units:

• 1 vega (symbol veg) is a speed of 1 pada per 1 agrima (pad · agm⁻¹; pad / agm), or 1 pada times 1 avrita (pad · vrt);
• 1 tevara (symbol tvr) is an acceleration of 1 pada per 1 square agrima (pad · agm⁻²; pad / agm²), or 1 pada times 1 square avrita (pad · vrt²);
• 1 keshe (symbol ksh) is an area of 1 square pada (pad²);
• 1 aytan (symbol ayt) is a volume of 1 cubic pada (pad³);

Pay attention that, for the square and cubic units, prefixes act on the unit itself, so that:

• 1 Cksh / ⁴ksh = 1 Dpad² / ²pad² = 1,0000 ksh = 1,0000 pad²,
  but 1 Cpad² / ⁴pad² = 1 EDksh / ¹²ksh = 1,0000,0000 ksh = 1,0000,0000 pad²
• 1 cksh / ₄ksh = 1 dpad² / ₂pad² = 0.0001 ksh = 0.0001 pad²,
  but 1 cpad² / ₄pad² = edksh / ₁₂ksh = 0.0000 0001 ksh = 0.0000 0001 pad²
• 1 Cayt / ⁴ayt = 10 Epad³ ¹pad³ = 1,0000 ayt = 1,0000 pad³,
  but 1 Cpad^{3 4}pad³ = 1 DSayt ²⁰ayt = 1,0000,0000,0000 ayt = 1,0000,0000,0000 pad³
• 1 cayt / ₄ayt = 0.1 epad³ / ₁pad³ = 0.0001 ayt = 0.0001 pad³,
  but 1 cpad³ / ₄pad³ = 1 dsayt / ₂₀ayt = 0.0000 0000 0001 ayt = 0.0000 0000 0001 pad³

For civil or day-to-day measure of volume, it may be more convenient to deal with a smaller, even though non-coherent, unit:

• 1 varti (symbol vrt) is a volume of 1 chatiaytan / cayt / ₄ayt = 0.0001 0.000 7 7̅1̅6̅ ̅0̅4̅9̅ ̅3̅8̅2̅ aytan, that is equal to 0.0001 0.000 7 7̅1̅6̅ ̅0̅4̅9̅ ̅3̅8̅2̅ pad³.
