1 millimeter is 1/25 of an inch.If you have full metric set next metric size is 1/25 of an inch larger than previous. Standard sizes increase in 1/16 of an inch increments which is bigger than 1/25.
9/16 is 14.287mm so if 14mm does not work 15mm will work for sure.
3/8 is 9.525mm so if 9mm does not work 10mm will work for sure.
If you use 15mm socket on 9/16 head it will be .028 of an inch oversize
If you use 10mm socket on 3/8 head it will be .0187 of an inch oversize.
Can you live with that?
If USA actually switched in 1905 to metric system when they accepted the system we would not have this mess today.
