Convert Decimal Angles to Degrees and Minutes

An angle of 1º can be divided into 60 equal parts. 

Each of these parts is known as 1 minute (1').

So 60' = 1º

Example

Convert 42.45º  into an angle in degrees and minutes.

Answer

Just look at the part after the decimal point i.e. 0.45º

Use a calculator to work out 0.45 × 60 = 27

So 42.45º = 42º 27'

That's pretty simple, isn't it?
