Calculate distance between my home and point X in Google form (or google sheets)

I try to create a Google form for my business as a painter so I can set data like from which hour till which hour a worked on a specific day, which products I used but also I want to know what the distance is between my home and the house I'm working that day. I presume it woul be best to have this information in Google Spreadsheet with an API formula or how do I do this best? And which formula do I need and which API key to set A) my hom till B) the house I'm working that day? Thanks for your help
