About this calculator
The ri was a traditional Japanese unit of distance, standardized during the Edo period as 36 chō, which fixes it at exactly 1 ri = 3.927 kilometers — noticeably longer than the Chinese li it’s historically related to. It was the standard unit for measuring road and travel distances between towns before Japan adopted the metric system.
Historians, translators, and readers of classical Japanese literature and old maps still encounter ri as a distance unit and need to convert it to make sense of the actual scale involved. This calculator converts between ri and kilometers in either direction using the 3.927 km conversion factor.
