Why 1% incline?

Indoors there is no air resistance and the belt helps your legs turn over, so a flat treadmill run is slightly easier than the same pace outside. Setting the incline to 1% is the long-standing fix that makes the effort line up with flat ground. Steeper than that and you are genuinely climbing, which this converter accounts for.
