Edo-Period Distance Conversions to Meters
Convert the distance units used in the Edo period (ri, chō, ken) to meters (m).
| Conversion to meters = | m |
1 ri is taken as 3927.2688m, based on the conversion 1 ri = 36 cho = 2,160 ken.
In the Edo period, 1 ri was the distance that could be walked in half a koku (approximately one hour). Therefore, the actual distance varied depending on the region and location. Although ri were also used for maritime routes, measuring distances was difficult, and the margin of error appears to have increased with greater distances.
