===== Lindogram =====

The unit of mass of SL physics engine. It is equivalent to 100 kg. The default 0.5×0.5×0.5 box weighs 1.25 Lindograms (125 kg) because the default density is 1000 kg/m³ (10 lindograms/m³).

Most physics functions work with a fundamental unit system in metres, lindograms and seconds as opposed to the [[http://en.wikipedia.org/wiki/MKS_system_of_units|MKS]] fundamental unit system which uses metres, kilograms and seconds.

For example, $lfn[llGetMass] and $lfn[llGetObjectMass] return the values in Lindograms. $lfn[llApplyImpulse] requires an impulse in Lindograms·m/s.

The exceptions are:

  * $lfn[llSetPhysicsMaterial] sets the density in kg/m³ rather than lindograms/m³.
  * $lfn[llGetMassMKS] returns kg instead of Lindograms.
