Manday is a unit of measurement, that refers to the amount of work done by one person in one day.

Generally, one manday is understood as an 8 hour period of work, but the amount of time may vary.

The abbreviation of Manday is MD.

Manday per hectare can be explained as the amount of work done per 1 hectare.

Calculation could be:

1 MD = 8 Hours

1 hour 50 minutes worked by 2 persons = 3 hours 40 minutes worked in total = 3.66 Hours

3.66 hours = 0.4575 MD ( 3.66 / 8 )

Mandays per hectare = Mandays worked / Area in hectares

Mandays per hectare = 0.4575 / 2.8 = 0.16339 MD/Ha
