Buyō uses the following measures (the U.S. and metric equivalents are approximate):
1 sun: 1 in; 3 cm
1 shaku: 1 ft; 30 cm (10 sun)
1 ken: 6 ft; 1.82 m (6 shaku)
1 ri: 2.4 miles; 3.93 km
1 tsubo: 36 ft2; 3.3 m2 (1 sq. ken)
1 tan: 0.25 acres; 1,000 m2 (300 tsubo)
1 chō: 2.45 acres; 1 ha (10 tan)
1 shō: 1.6 quarts; 1.8 L
1 koku: 5 bushels; 180 L (100 shō)
One hyō (bale) varied in quantity regionally between one-fifth and one-half of a koku; Buyō counts 1 hyō as roughly equivalent to one-third of a koku.
