Earth measurements are used as the standard units of measure used in the United Federation of Planets.

It is possible that the UFP does not actually use Earth measurements, but that their usage on screen is an example of "implicit translation" (such as the characters in the film Template:IMDb-name speaking English when the viewer understands that they are "speaking" Russian.) This is implied by scenes such as the one where Kirk remarks to Abraham Lincoln that the Enterprise could convert to minutes. (TOS: "The Savage Curtain")

Length

Meter

A meter (m) is the fundamental SI unit of length, defined as the distance traveled by light in a vacuum in 1/299,792,458 second.

In the Imperial units system 1 foot ≡ 0.3048 m.

See also: Meter at Wikipedia

centimeter

A centimeter (cm) is an SI unit of length equal to 1/100 of a meter.

1 cm ≈ 0.39370 inches.

See also: Centimeter at Wikipedia

kilometer

A kilometer (km) is an SI unit of length equal to one thousand meters.

1 km ≈ 0.62137 miles.

See also: Kilometer at Wikipedia

millimeter

A millimeter (mm) is an SI unit of length equal to 1/1,000 of a meter.

1 mm ≈ 0.03937 inches.

See also: Millimeter at Wikipedia

Micron

A micron is another name for micrometer (µm), an SI unit of length equal to 1 millionth of a meter (1e−6×10−6 m).

1 mil ≡ 25.4 μm.

See also: Micrometer at Wikipedia

Mile

A mile (mi) was originally one thousand paces, or 5,000 Roman feet (~4,850 Imperial feet). A later British reform changed the mile to 5,280 Imperial feet so that it would equal eight furlongs.

1 mi ≡ 1.609344 km.

See also: Mile at Wikipedia

Nautical Mile

A nautical mile was based on the length of one minute of arc of a great circle.

1 nautical mile = 1852 m (6076.12 ft)

Foot

A foot (ft, plural feet) is an Imperial unit of length equal to twelve inches, or one third of a yard.

1 ft ≡ 0.3048 m.

See also: Foot at Wikipedia

Inch

An inch (in) was originally based on the width of the average man's thumb, or the length of three barleycorns. It was later redefined based on SI units.

1 in ≡ 2.54 cm.

See also: Inch at Wikipedia

Light year

(Main Article: Light year)

One light year is the distance that light travels in one Earth year. It is approximately equal to 9.46e15×1015 meters, or 5.88e12×1012 miles.

Mass

Kilogram

A kilogram (kg) is the fundamental SI unit of mass.

In the Imperial units system 1 pound ≡ 0.45359237 kg.

See also: Kilogram at Wikipedia

Gram

A gram (g) is an SI unit of mass equal to 1/1,000 of a kilogram.

1 ounce ≡ 28.349523 g.

See also: Gram at Wikipedia

Milligram

A milligram (mg) is an SI unit of mass equal to 1/1,000 of a gram.

See also: Milligram at Wikipedia

Time

See: Time measurements

Volume

Liter

A liter (L or l) is a derived SI unit of volume, equal to 1/1,000 cubic meters (1 cubic decimeter).

In the Imperial units system 1 gallon ≡ 4.54609 L (~277.42 cubic inches).

In the US system, 1 gallon ≡ 231 cubic inches ≡ 3.785411784 l.

See also: Liter at Wikipedia

milliliter

A milliliter (ml) is an SI unit of volume equal to 1/1,000 of a liter.

In the Imperial system 1 fluid ounce ≡ 28.4130625 ml.

In the US system, 1 fluid ounce ≡ 29.5735295625 ml.

See also: Milliliter at Wikipedia

cc

A cc (cubic centimeter, official cm3) is a measure of volume equal to one cubic centimeter (cm), which is also equal to one milliliter (ml). The cc is a common term for milliliter used in measuring the dosage of liquid medicines by volume.

1 cubic inch ≡ 16.387964 ml ≡ 16.387964 cc.
