Equalities and Inequalities in the Standard Units Environment
Description
Examples
In the Standard Units environment, the equality and inequality operators (=,<,≤,>,≥, and≠) are modified so that they perform the necessary operations on expressions with units.
The properties of the five arithmetic operations are:
AUnita=BUnitb→A=rB
AUnita<BUnitb→A<rB
AUnita≤BUnitb→A≤rB
AUnita>BUnitb→A>rB
AUnita≥BUnitb→A≥rB
AUnita≠BUnitb→A≠rB
where a and b are units; A and B are coefficients; and r is the conversion factor from the unit b to the unit a.
Notes:
To enter a unit in 2-D Math input, select the unit from the appropriate Units palette. If the unit you want is not there, select unit and then enter the unit.
When you edit a unit, double brackets appear around it.
