I take your point, I think. But neither is helpful unless you have a benchmark in mind. Off the top of my head I couldn't say how many metres per revolution would make a middling sort of gear for a single speed bike, but I'd say 70 inches according to the UK way. And I can remember my dad talking about 130" top gears on racing bikes If I wanted to give you the metric version I'd have to multiply by Pi and convert to metres.
What would be even less meaningful would be the actual gear ratio, mainly because it would be different for every wheel size.
I also find the idea of someone riding a penny farthing with a 10' wheel funny, even though he would find it impossible unless he had a 65"+ inside leg.
