Converting Roman feet to miles

To convert Roman feet to miles, multiply the value by approximately 0.00018376. 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.

Visual unit comparison

Relative scale

1 Roman foot is approximately 0.00018376 miles.

1 mile is approximately 5441.8 Roman feet.

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.

Roman Foot (pes)

The Roman foot, or pes, was the base length unit of the Roman measuring system.

Historical context
The pes was divided into 12 unciae (inches) or 16 digiti (finger widths). Surviving measuring rods and building surveys place it very close to 296 mm, with small local variations across the empire.
Where it was used
Used for architecture, road building, aqueducts and land survey throughout the Roman world, and still referenced today when studying classical buildings.
Approximate modern equivalent
Approximately 0.2957 m, roughly 29.6 cm or 11.64 inches.

Mile (mi)

The mile (mi) is the imperial long-distance unit, equal to 5,280 feet.

Origin
Descended from the Roman mille passus but lengthened by later English statute, and fixed at exactly 1,609.344 m.
Where it is used
Used for road distance, transport planning and site context in the US and UK.
Relation to SI
1 mi = 1,609.344 m exactly.

Frequently asked questions

How many miles are in one Roman foot?

1 pes is approximately 0.00018376 mi.

How do I convert Roman feet to miles?

Multiply the value by approximately 0.00018376. For example, 10 pes is approximately 0.0018376 mi.

How do I convert back from miles to Roman feet?

1 mi is approximately 5441.8 pes. The converter above works in both directions, so you can type into either field.

Why do historical measurements vary?

Ancient units were tied to body proportions and local standards rather than a central definition, so their length drifted between regions, workshops and centuries.

How accurate are these historical values?

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.

Why are ancient units still referenced today?

They explain the proportions of surviving buildings. Reading a temple or basilica in its original unit reveals design grids that look arbitrary in meters.
