Why are there different types of British thermal units in this conversion?

Because the thermochemical Btu and International Table Btu have slightly different energy definitions, relevant in various engineering and scientific contexts.

Can this converter be used for any area unit?

No, it specifically requires the area unit to be square foot for consistent and valid results.

What is the main time unit difference in this conversion?

The conversion changes the rate of heat transfer from a per second basis to a per minute basis.
