Inches to Yards
To convert an inch measurement to a yard, divide the length by the conversion ratio. We know that 1 yard is equal to 36 inches, so use this formula to convert.
Yards = inches ÷ 36
Ex- Convert 5 inches to yards.

Standard Unit of Length
The standard unit of length is meter(m).
A meter length can be divided into 100 equal parts.
Each part is known as centimetre and written in short as ‘cm’.
Therefore, 1 m = 100 cm and 100 cm = 1 m
Miles to Kilometers
To convert from miles to kilometers we should use 1 mile is equivalent to 1.609344 kilometres.
Ex-Convert 5 miles to kilometres.
Sol: We know that 1 mile = 1.6093444 kilometres.
Hence 5 mile = 5 × 1.609344= 8.04672 km.
