Element psr:ExtendedUnit / psr:dimEquation
Namespace http://voparis-europlanet.obspm.fr/xml/PSR/v1.0
Annotations
 
Dimensional equation representation of the unit, formatted as
a string where M is mass, L is length, T is time, K is temperature, and Q
electric charge. For ease of notation , the caret "^" indicating powers of
ten can be removed - as is customary in Dimentional Analysis practices -
resulting in expressions like the following, which are equivalent: "ML-1T-3"
and "ML^-1T^-3"
