Fill in the fields above and click Calculate.
Formula
Raw Time (min) = (Area × Soil Factor × Method Factor × Obstacle Factor) ÷ Base Rate
Adjusted Time (min) = Raw Time ÷ Number of Workers
Where Base Rate = 0.833 m²/min (~50 m²/hr), representing a single worker
performing standard mopping on a lightly soiled, open surface.
