None. A metre is a measure of length or distance while 10base2 is a pure, dimensionless number.
185 meters
10Base2 is also known as Thin Ethernet
The maximum length of a 10Base2 thinwire ethernet cable is 185 ft.
For 10Base2, the 10 stands for 10 megabits per second, Base means baseband, and 2 equals 200 meters

500m, for 10Base5 thicknet - probably no installations left. For 10base2 thinnet, it's around 185 m - maybe some that have not moved on to twisted-pair of some kind..
