it is necessary to convert all quantities to a consistent set of units before performing any calculations

True or false

True otherwise the calculations may go wrong.

Example:

A train covers a distance of 300 miles in 50 minutes,then find the speed of the train in mph?

Sol: Given distance covered=300 miles

Time taken to cover the distance= 50min

Speed=Distance/Time

=300/50 mi/min

Here time is in minutes.It should be convert into hours otherwise the calculation of speed is not correct one.

Speed= 300/50

=300/50/60

=300*60/50

=360 mph

Hence,before performing any calculations it is necessary to convert all quantities to a consistent set of units.

So, the answer is TRUE.
