I want to make a VBA function that will return a value in decimal degrees, using the degree, minutes and seconds values in the three cells to the left of any cell in which I choose enter the function. Essentially. it will perform the calculation

Decimal degrees = degrees + minutes/60 + seconds/ 3600

As for example here:

D M S Decimal degrees
3 33 56 3.56555556

I have made a number of relevant searches, but the answers seem considerably more complicated than I would have expected. Surely there must be a simple VBA method to retrieve the values one, two, and three spaces to the left of the cell in which the function is entered?
