You can't compare the 2 numbers - it's like reading the temperature in Celsius vs Fahrenheit. The temp is the same, the numbers are just different. If using a human meter, 'normal' range is 50-120 while a pet meter 'normal' is 80-140(ish). You don't need to do any 'conversions'. Just note on your spreadsheet that you're using a human meter....good thing to add it to your signature also - that's where people will look first.
