Earth measurements were the standard units of measure used in the United Federation of Planets.
Length
Meter
A meter (m) was 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.
Millimeter
A millimeter (mm) was an SI unit of length equal to 1/1,000 of a meter.
1 mm ≈ 0.03937 inches.
- See also: Millimeter at Wikipedia
Centimeter
A centimeter (cm) was 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) was an SI unit of length equal to one thousand meters.
1 km ≈ 0.62137 miles.
Micron
A micron was another name for micrometer (µm), an SI unit of length equal to 1 millionth of a meter (1
×10−6 m).1 mil ≡ 25.4 μm.
- See also: Micrometer at Wikipedia
Mile
(Main article: 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.
Nautical mile
A nautical mile was based on the length of one minute of arc of a great circle.
1 nautical mile ≡ 1,852 m (∼6,076.12 ft)
- See also: Nautical mile at Wikipedia
Foot
A foot (ft, plural feet) was an Imperial unit of length equal to twelve inches, or one third of a yard.
1 ft ≡ 0.3048 m.
Inch
An inch (in) was originally based on the width of the average man's thumb, or the length of three barley-corns. It was later redefined based on SI units.
1 in ≡ 2.54 cm.
Light year
(Main article: Light year)
One light year was the distance that light traveled in one Earth year. It was approximately equal to 9.46
×1015 meters, or 5.88 ×1012 miles.Mass
Kilogram
A kilogram (kg) was the fundamental SI unit of mass.
In the Imperial units system, 1 pound ≡ 0.45359237 kg.
Gram
A gram (g) was an SI unit of mass equal to 1/1,000 of a kilogram.
1 ounce ≡ 28.349523125 g.
Milligram
A milligram (mg) was an SI unit of mass equal to 1/1,000 of a gram.
Time
See: Time measurements
Volume
Liter
A liter (L or l) was 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.
Milliliter
A milliliter (ml) was 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) was a measure of volume equal to one cubic centimeter (cm3), which was also equal to one milliliter (ml). The cc was a common term for milliliters used in measuring the dosage of liquid medicines by volume.
1 cubic inch ≡ 16.387064 ml ≡ 16.387064 cc.
Cubic meter
During a sensor sweep of the neutral zone, the USS Enterprise-E found 25 particles of dust per cubic meter. (Star Trek: First Contact)
Units
Gross
A gross was equal to a dozen dozen.
