Default Ohms law brain freeze

I should know this but I just can't get my brain around it.

I have a data logger that will accept 4-20 mA or 0-2.5VDC. I want to track
the current going to the refrigeration compressor which I figure will be in
the range of 0 to 25 amps (to be safe for start ups).

What is the best way to accomplish this?
