Biblical Cubits to Centimeters (cubit to cm)

1 biblical cubit equals 54 centimeters exactly.

1 biblical cubit = 54 centimeters

How to convert biblical cubits to centimeters

To convert biblical cubits to centimeters, multiply the number of biblical cubits by 54. This factor is exact. To go the other way, multiply centimeters by 0.01851851852 (rounded).

centimeters = biblical cubits × 54

Example: 10 biblical cubits = 540 centimeters.

About these units

Biblical Cubit (cubit)

Biblical (Hebrew)Historical unit (no longer in standard use)Approximate value

The cubit of the Hebrew Bible, taken here as the rabbinic cubit of about 54 cm (21 in). Estimates range from about 48 cm to 57.6 cm, so the exact value is debated.

Latin cubitum means elbow, and the cubit began as the span from elbow to fingertip. The Hebrew term is amah. The Bible gives measurements in cubits for Noah's Ark, the Tabernacle and Solomon's Temple, so the length matters to anyone trying to reconstruct them. Since arms differ, the unit varied by country and era, and no single figure is certain.

In the second century CE the rabbis defined a cubit as six handbreadths, each of four fingerbreadths, which gives roughly 54 cm. Later authorities disagree: Avraham Chaim Naeh calculated 48 cm, and the Chazon Ish 57.6 cm. Maimonides also described a shorter cubit of five handbreadths for measuring the altar. The 54 cm rabbinic figure is the one used here. A rough modern comparison is the length of a forearm and a hand, or between 19 and 23 inches.

1 biblical cubit = 0.54 meters (approximately).

Centimeter (cm)

Metric (SI)Current unit

One hundredth of a meter. Used for body measurements, clothing and everyday objects.

Scientists, rather than shopkeepers, gave the centimeter its place. In 1832 Carl Friedrich Gauss proposed a system of absolute units built on length, mass and time, choosing the millimeter, milligram and second. In 1873 a committee of the British Association for the Advancement of Science, whose members included James Clerk Maxwell and William Thomson (Lord Kelvin), recommended the centimeter, gram and second instead. That CGS system dominated physics for decades, until the metre-kilogram-second system replaced it in the mid-twentieth century and led to SI.

CGS units proved awkward for rooms and buildings, which run to hundreds of centimeters, but the centimeter itself never went away. It is still the everyday unit for height, clothing and small objects, and it appears in map scales and rainfall reports. An adult fingernail is roughly one centimeter wide, and a milliliter is defined as exactly one cubic centimeter. An inch is exactly 2.54 centimeters. The CGS system itself survives mainly in theoretical physics and astrophysics, where Gaussian units are still common.

1 centimeter = 0.01 meters (exactly).
