Sabbath Days' Journeys to Millimeters (sabbath to mm)

1 Sabbath day's journey equals 1,080,000 millimeters exactly.

1 Sabbath day's journey = 1,080,000 millimeters

How to convert Sabbath days' journeys to millimeters

To convert Sabbath days' journeys to millimeters, multiply the number of Sabbath days' journeys by 1,080,000. This factor is exact. To go the other way, multiply millimeters by 9.259259259×10⁻⁷ (rounded).

millimeters = Sabbath days' journeys × 1,080,000

Example: 10 Sabbath days' journeys = 10,800,000 millimeters.

About these units

Sabbath Day's Journey (sabbath)

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

About 2,000 cubits (roughly 1.08 km), the distance a person could walk on the Sabbath according to rabbinic tradition.

Jewish law limits how far a person may travel from a town on the Sabbath, and that limit is the techum shabbat. It is set at 2,000 cubits beyond the settlement boundary, the same distance known as a biblical mile. The phrase Sabbath day's journey is the traditional English name, and the distance was also used to measure the spacing of towns in the Herodian era, for instance Sepphoris to Tiberias at 18 such miles.

The metric value depends on the cubit chosen. Taking a cubit of 46 to 60 cm gives a range of about 960 m to 1,152 m, and the figure used here, about 1.08 km, comes from the 54 cm rabbinic cubit. That is about two thirds of an English statute mile, or roughly six Greek stadia. Most authorities reckon it at about 18 minutes of walking, while Maimonides gave 20 to 24 minutes. An eruv techumin can add a second mile to the permitted limit.

1 Sabbath day's journey = 1,080 meters (approximately).

Millimeter (mm)

Metric (SI)Current unit

One thousandth of a meter. Used in engineering, manufacturing and rainfall measurement.

Carl Friedrich Gauss put the millimeter at the base of his 1832 proposal for absolute units, pairing it with the milligram and the second, although the centimeter-based CGS system later won out among scientists. The name combines the metric prefix milli-, from the Latin for one thousand, with the meter. Since 1983 a millimeter has been tied to the speed of light: it is the distance light covers in 1/299,792,458,000 of a second.

Millimeters are the language of fine mechanical work. Standard rulers are divided into them, digital calipers commonly read to 0.01 mm, and mechanical pencil leads come in 0.5 and 0.7 mm. Copy paper is about 0.1 mm thick, and a thin hair, at 0.02 to 0.04 mm across, is close to the smallest thing the naked eye can see. A wave with a frequency of 300 GHz has a wavelength of 1 mm. An inch is exactly 25.4 mm. One trap for readers in the United States is that mil there traditionally means a thousandth of an inch, not a millimeter.

1 millimeter = 0.001 meters (exactly).
