Scandinavian Mil to Millimeters (mil to mm)

1 Scandinavian mil equals 10,000,000 millimeters exactly.

1 Scandinavian mil = 10,000,000 millimeters

How to convert Scandinavian mil to millimeters

To convert Scandinavian mil to millimeters, multiply the number of Scandinavian mil by 10,000,000. This factor is exact. To go the other way, multiply millimeters by 1×10⁻⁷.

millimeters = Scandinavian mil × 10,000,000

Example: 10 Scandinavian mil = 100,000,000 millimeters.

About these units

Scandinavian Mil (mil)

ScandinavianTraditional unit (still used in some regions)

Exactly 10 kilometers. Sweden and Norway still quote car distances and fuel consumption in 'mil' (not to be confused with the 'mil' for a thousandth of an inch).

Swedes and Norwegians still say that a town is a few mil away, and the word comes from the same Roman source as the English mile. Today one mil is exactly 10 kilometers, a figure Norway fixed when it adopted the metric system in 1875 and Sweden followed in 1889. Finland redefined its own peninkulma as 10 kilometers in 1887.

The older mil was far less tidy. In 1649 Sweden made the Uppland mile, about 10,688.5 meters, its unit mile, though counties kept their own, such as 14,485 meters in Dalarna. After the 1814 union, Norway's mil worked out at about 11,295 meters. Denmark used a shorter one of 7,532.4 meters, standardized in 1683 by Ole Rømer and equal to four minutes of latitude.

Road signs use kilometers, but speech does not. Five kilometers is half a mil, used-car adverts quote odometer readings in mil, and the Swedish Tax Agency counts some deductions in them.

1 Scandinavian mil = 10,000 meters (exactly).

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).
