300nm to km

Ah, the classic nautical mile conundrum. One nautical mile (nm) is exactly 1.852 kilometres. So, if you're converting 300 nm, multiply 300 by 1.852 and voilà: 555.6 km. That’s roughly the distance from Sydney to Canberra, if you’re wondering. Always handy to know whether you’re measuring sea or land distances, lest you end up in the wrong place.
