Roughly Speaking, what is the equivalent of 10k steps on an incline treadmill walk?

Using my build (6 feet roughly 160 pounds), how many steps on a treadmill on an incline of 10 and let’s say 3.3 mph speed, would match the general caloric burn of 10k steps on flat ground?

Then further, let’s say I walk 100 steps per minute, how long would it take for me to achieve the same caloric burn (simple calculation I know after the fist ask lol, but figured just to wrap it all up in 1 answer)
