Converting Roman feet to meters

To convert Roman feet to meters, multiply the value by approximately 0.29574. 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

To scale

1 Roman foot is approximately 0.29574 meters.

1 meter is approximately 3.3813 Roman feet.

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.

Meter (m)

The meter (m) is the SI base unit of length and the international standard used worldwide.

Origin
Originally defined as one ten-millionth of the distance from the equator to the North Pole, it is now defined by the distance light travels in vacuum in 1/299,792,458 of a second.
Where it is used
Used for building grids, floor levels, spans, site dimensions and virtually all scientific and engineering work.
Relation to SI
The meter is the SI base unit; every other length unit here is defined from it.

Frequently asked questions

How many meters are in one Roman foot?

1 pes is approximately 0.29574 m.

How do I convert Roman feet to meters?

Multiply the value by approximately 0.29574. For example, 10 pes is approximately 2.9574 m.

How do I convert back from meters to Roman feet?

1 m is approximately 3.3813 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.

Is this length converter free to use?

Yes. Every unit conversion runs in your browser, needs no account and is free for professional use.
