On average, what percentage of the Earth is on fire?

The recent wildfires got me thinking. Wildfires are BIG. I wouldn't guess this number to be too big, but if even 1% of my home were on fire, that'd be a huge deal.

Well, the earth is 197M square miles, 140 of then being ocean. That leaves 57M square miles. That's 37.5B acres.

The largest wildfire in history burned 3M acres. So...you would need 125 of those burning at the same time to hit 1%.

How's that?
