Calories vs activity and time vs. distance

I've started a spreadsheet where I input activity, mileage, minutes of activity, calories burned per the S Health app on my phone.

So far, the range of calories burned per mile travelled for

• Cycling  41-43
• Hiking 94-95.4
• Walking 79-100

Calories per minute:

• Cycling  9-10.5
• Hiking 4.7-5.1
• Walking 4.1-5.0
