BURR,

That's why most home {diy} mechanics have both
a Set of Metrics and a Set of SAE Tools . . .

Just like having a common Slotted [Flat] Screwdriver
and a Phillips [Pointed] Screwdriver; but please don't
try to use a Phillips on a Reed-and-Prince Screw Head.

Plus there are Allen Wrenches [Hex-Key/Head] in both
SAE and Metric Sizes too.

often in spite of all the 'metric' and 'sae' tools and
other fancy devices . . . it all comes down to . . .
