The following formula gives the temperature's measure in degrees Fahrenheit F, where ‍C is the measure in degrees Celsius:

\(F=\frac{9}{5}C+32\)

Rearrange the formula to highlight the measure in degrees Celsius.
The following formula is used in economics to find a factory's unit labor cost ‍U, where ‍O is the hourly output per worker and ‍W is the hourly compensation per worker.

\(U = \frac{W}{O}\)

Rearrange the formula to highlight the hourly output per worker.
The following formula gives the area ‍A of a trapezoid, where ‍b and ‍c are the bases of the trapezoid and ‍h is the height:

\(A=\frac{1}{2}(b+c)h\)

Rearrange the formula to highlight the height.
The following formula gives an object's average speed ‍S, where ‍T is the time it takes the object to travel a distance ‍D.

\(S=\frac{D}{T}\)
Rearrange the formula to highlight time.
