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).

Inch (in)

US & ImperialCurrent unit

1/12 of a foot. Defined as exactly 25.4 millimeters since 1959, when the US and Commonwealth countries agreed a common international inch.

Latin uncia, meaning one-twelfth, is the root of both inch and ounce, and it passed into Old English as ynce. Roman measurers divided their foot into twelve unciae, and the English inch kept that twelfth. After 1066 an inch was reckoned as three barleycorns, and a 1324 statute attributed to Edward II spelled out the definition as three grains of barley, dry and round, placed end to end lengthwise. For centuries the inch was simply a twelfth of a foot, or a thirty-sixth of a yard, and the US and UK each kept their own copy of the standard yard.

Those copies differed slightly until the 1959 international agreement fixed the yard at exactly 0.9144 meter, which made the inch exactly 25.4 millimeters. The US adopted it in 1959 and the UK ratified it in 1963, effective 1964. Today the inch is still the customary unit in the United States and Canada, and the UK keeps it on road signs. Worldwide it also names display diagonals, wheel rims, tire codes and pipe sizes.

1 inch = 0.0254 meters (exactly).
