Understanding questions as a foreign medical graduate?

I struggle with some of the units and I’m a foreign medical graduate and in my home country we use different measurements. Did anyone else find that it takes a few extra seconds to convert stuff in your head or look at the values tab? For example, we use HbA1c as number values, not as a %, so for 19 years it’s hard to change all of these values around to this system. Granted, some Qs give both values so that helps!
