Its a piece of land given to a person in medeival society to rule on and to raise a small army to help the king of the country. I made a standard for the size of land that is suitable for one such unit. I named it estate or village. 1 estate is a square 1 mil long and 1 mil wide. Note that 1 mil is equal to 2 km. 1 estate is therefore equal to 4 sq km or 1000 acres. It means its enough for

An acre is amount of land that one person can plow once in one day using one pair of bulls pulling a plow. It is standardized as 4000 sq meters. One meter is also the amount of land that is needed to support one person for one year, if:(1) There is only one crop per year. (2) Land is average (grow 400 kg of wheat a crop for example).(3) Rain is the only source of water that is used, that is,

On the basis of unit of length "zira", we can have a unit of mass too. Mass of one cubic zira water is 125 kg, this is a traditional arabic unit of mass, its called wasq. One wasq is equal to 1000 oqia where one oqia is equal to 125 grams. Wasq and oqia can easily be seen in daily life. Some examples are:(1) One wasq is the maximum weight a man, usually a wrestler can have with health. (2) One

The unit "meter" has no fundamental justification. Its hard to approximate for a layman what a meter is. There is another unit called "zira" which is far more understandable and easy. Infact, "zira" is the unit of length which is the

Desert having little water has little fertility whereas deltas of nile, euphrates, ganges and indus have high fertility due to water availability. There are infact three sources of water, primary which is rain,
