The old thinking was 40 cal/mile. That would work out to 125 cal/5 km.
But they're rethinking that, and dropping it to 30 cal/mile, which works out to about 94 cal/5 km. Some even say as low as 25 cal/mile which is only about 78 cal/5 km.
But the 100 cal/5 km is reasonably ballpark.
And links like the one you've linked to ... notoriously over-estimated like most of them.
