Greek Foot (pous)

The Greek foot, or pous, was the base unit of ancient Greek metrology.

Historical context
Several regional standards existed. The Attic pous used here is about 308 mm, a value derived from the stylobate dimensions of classical temples.
Where it was used
Used for temple design, city planning and stadium layout in the Greek world; 600 podes defined a stadion.
Approximate modern equivalent
Approximately 0.3083 m, roughly 30.8 cm or 12.14 inches.

Roman Cubit (cubitum)

The Roman cubit, or cubitum, measured the forearm from elbow to fingertip and equalled one and a half Roman feet.

Historical context
Defined as 1.5 pes, the cubitum sat between the foot and the pace in the Roman scale and was inherited from earlier Mediterranean cubit systems.
Where it was used
Common in carpentry, masonry and textile trades, and used in written descriptions of building dimensions.
Approximate modern equivalent
Approximately 0.4436 m, roughly 44.4 cm or 17.5 inches.

Frequently asked questions

How many Roman cubits are in one Greek foot?

1 pous is approximately 0.69493 cubitum.

How do I convert Greek feet to Roman cubits?

Multiply the value by approximately 0.69493. For example, 10 pous is approximately 6.9493 cubitum.

How do I convert back from Roman cubits to Greek feet?

1 cubitum is approximately 1.439 pous. 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.
