There seems to be an error regarding logical statements in Prime 10.0.1. See below.
The expected output of all statements is 1. It seems to only be a problem when using units.
Is there a fix to this? Thanks

What you experience is a combination of inaccuracies in unit conversion (even though its only a multiplication by 10^-3 as Prime is always going back to the base units) and the 'natural' accuracy limit of the IEEEE number format used.
A 'fix" is to use a system which is using a number format which can provide more accuracy then the typical 14-16 decimals of the IEEE storage format.
Primes built-in symbolic engine provides more accuracy and could be used. Using the symbolic evaluation (->) instead of the numeric (=) one gives the correct result for your example. You may want to check "Unit/Constants in Symbolics" in the Calculation Options.
Sometimes it may be necessary to add the "simplify" modifier to get a meaningful result:
