Instant, two-way conversion across common engineering units.
1 in = 0.01717725 passus(Inch → Roman Pace (Passus))
To convert inches to Roman paces, multiply the value by approximately 0.017177. Ancient units were reconstructed from surviving rods, buildings and written sources, so treat every result as a close approximation rather than an exact figure. Historical measurements varied by period and region, so this converter uses commonly accepted reference values.
Relative scale
1 inch is approximately 0.017177 Roman paces.
1 Roman pace is approximately 58.217 inches.
Visual scale compressed because of the large difference between the units. The bars above are not drawn to exact scale; the numeric relationship above is exact within the commonly accepted reference values.
The inch (in) is the base small unit of the imperial and US customary length system.
The Roman pace, or passus, was a double step measured from one heel strike to the next by the same foot.
1 in is approximately 0.017177 passus.
Multiply the value by approximately 0.017177. For example, 10 in is approximately 0.17177 passus.
1 passus is approximately 58.217 in. The converter above works in both directions, so you can type into either field.
Ancient units were tied to body proportions and local standards rather than a central definition, so their length drifted between regions, workshops and centuries.
Historical measurements varied by period and region. This converter uses commonly accepted reference values for educational and professional use, so every result should be read as an approximation rather than an exact equivalence.
They explain the proportions of surviving buildings. Reading a temple or basilica in its original unit reveals design grids that look arbitrary in meters.
