Metric vs Imperial Questions

So while studying using the official ISC2 adaptive learning I came across this question.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.4-2019 recommends setting the temperature ranges for maximum uptime and hardware life as between which of the following?

A - 50⁰ and 81⁰ F

B - 64⁰ and 70⁰ F

C - 50⁰ and 70⁰ F

D - 64⁰ and 81⁰ F

When I read this in the study notes I noted in my head the 18 to 27 degrees Celsius. I did not memorise the 64 to 81 F as I do not understand Fahrenheit.

So do I need to learn to convert Imperial to Metric in my head as I will not have access to a calculator in the exam? Or will the actual questions in the Exam have both Imperial and Metric?
