Hi,I'm a civil engineer and I like to use ConTeXt to write my report etc.As engineer i use a lot of units in my writing and the \unit command works nice with this.What I need is a new unit, a quadratic unit like this:Area Moment of Inertia - Metric units mm4 cm4 m4This kind of units are quite common in civil engineer.This is an example of what i want in ConTeXt\starttext\unit{230.00 m^2}\unit{230.00 m^3}\unit{230.00 m^4}\stoptextThank youGiuseppe Fierro
