WebUnits of measurement let us describe and compare length, weight, area, volume, density and other values. Units can be imperial or metric and they can be converted using conversion factors. WebSolved Examples. Example 1: Find the number of minutes in a day. Solution: A day has 24 hours. We know that an hour has 60 minutes. We must find the number of minutes in 24 hours. Number of minutes in a day = Number of minutes in 24 hours. = Number of minutes in 1 hour \ ( \times~24\) \ ( =60\times~24\) =1440 minutes. lawn mower front hitch
