Wrench sets designed for SI bolts often include wrenches at 1 mm increments while wrench sets designed for imperial bolts often

juin [17]

So 5/8 inches to milimeters
we know that 1 in=2.54 cm so
5/8 in times 2.54= 1.5875 cm
1 cm=10 mm
1.5875 cm times 10=15.875mm aprox 16 mm, but best to go smaller since it won't fit if bigger

answer: 16mm (my recomendation would be 15mm)
