Measure of man:
The earliest and most primitive architectural living space was the minimum volume required to contain the family.  Its dimensions, therefore, were based on human measurements in their multiple, modified by interior functional activities and by the limits that material and technique imposed.

Notes: The smallest units, mō, rin and bu, are actually the names of fractions, 1⁄10000, 1⁄1000 and 1⁄100, respectively, which are also used as fractional units. The shaku is, in some cases, the Japanese equivalent to the foot.[5] The hiro is a unit of depth—the Japanese equivalent of the fathom.[citation needed] 1 chō = 60 ken ˜ 0.1091 kilometres ˜ 0.06779 miles 1 ri = 36 chō ˜ 3.927 kilometres ˜2.440 miles

Notes: Conversions to metric, imperial and US customary units are rounded to four significant figures. A jō is the size of one tatami mat-used in quoting room sizes. 1 tsubo = 1 square ken-used in construction. 1 bu = 1 square ken-used in agriculture. 1 tan ≈ 0.09917 hectares ≈ 0.2451 acres 1 chō ≈ 0.9917 hectares ≈ 2.451 acres

Notes: Conversions to metric, imperial and US customary units are rounded to four significant figures. The gō is a common size for serving sake. The shō (about 64.827 cubic sun) is a former common sake-bottle size (it is presently legally filled and labelled as 1800 mL). The koku (about 40.95 US dry gal) originally was the volume of rice a person would eat in one year.

Measurement in Mass:

kan or kanme	貫, 貫目	1000	3.75×106	3750	3.75	2116	132.3	8.267
Notes: Metric values are exact and conversions to avoirdupois units are rounded to four significant figures. Momme is the usual form, but strictly speaking the current romanization system dictates monme.
