Length Units Introduction
Nanometer (nm) equals one billionth of a meter (1 nm = 10^-9 m). It is commonly used to measure very small objects and structures, such as viruses, DNA, and materials in nanotechnology. Research at the nanoscale is significant in fields like electronics, biomedicine, and materials science.
Micrometer (μm) equals one millionth of a meter (1 μm = 10^-6 m). It is often used to measure tiny biological entities and structures, such as bacteria, cells, and small particles. Micrometer-level precision is crucial in biology and materials science.
Millimeter (mm) equals one thousandth of a meter (1 mm = 10^-3 m). It is commonly used to measure the length of small objects, such as the diameter of screws, the thickness of paper, and the dimensions of furniture components. In mechanical and engineering manufacturing, the millimeter is a common unit.
Centimeters (cm) equals one hundredth of a meter (1 cm = 10^-2 m). It is widely used in everyday life, such as measuring the width of books, height, and the size of objects. The centimeter is also a common unit in school education.
Meters (m) is the base unit of length in the International System of Units (SI). It is the foundation for many other units, such as millimeters, centimeters, and kilometers. The standard definition of a meter is the distance light travels in a vacuum in 1/299,792,458 seconds. The meter is widely used in science, engineering, and daily life.
Kilometers (km) equals one thousand meters (1 km = 10^3 m). It is commonly used to measure longer distances, such as the distance between cities, the length of roads, and geographical distances. The kilometer is also a common unit in running and motor racing.
Angstrom (Å) equals ten times one ten-billionth of a meter (1 Å = 10^-10 m). It is primarily used to measure the size of atoms and molecules, such as atomic radii and bond lengths in molecules. In structural biology and crystallography, the ångström is an important unit.
Inches (in) equals 2.54 centimeters (1 in = 2.54 cm). It is commonly used to measure screen sizes, paper dimensions, and the length of household items. In the United States and the United Kingdom, the inch is a common unit of length.
Yard (yd) equals 3 feet or 0.9144 meters (1 yd = 3 ft = 0.9144 m). It is commonly used to measure sports fields, fabric lengths, and swimming pool distances. The yard is widely used in English-speaking countries.
ft. U.S. (ft-us) equals 0.3048 meters (1 ft-us = 0.3048 m). It is commonly used in the United States to measure building heights, room dimensions, and short distances. The US survey foot is slightly different from the international foot but can be used interchangeably in most cases.
Feet (ft) equals 12 inches or 0.3048 meters (1 ft = 12 in = 0.3048 m). It is commonly used to measure heights, short distances, and building structures. In many English-speaking countries, the foot is a common unit.
Fathom (fathom) equals 6 feet or 1.8288 meters (1 fathom = 6 ft = 1.8288 m). It is primarily used to measure water depth. In maritime contexts, the fathom is an important unit for describing the depth of oceans and lakes.
Miles (mi) equals 5280 feet or approximately 1.609 kilometers (1 mi = 5280 ft = 1.609 km). It is commonly used to measure road and geographical distances, such as the distance between cities. In the United States and the United Kingdom, the mile is a common unit of length. It is also frequently used in running, motor racing, and nautical contexts.
Nautical Mile (nmi) equals 1852 meters (1 nmi = 1852 m). It is primarily used to measure nautical and aviation distances. The nautical mile is defined based on the Earth's latitude and longitude system, with one nautical mile approximately equal to one minute of latitude. In maritime and aviation navigation, the nautical mile is a standard unit.
Thousandth of an inch (thou) equals 0.001 inches (1 thou = 0.001 in). It is primarily used for precision measurements in mechanical engineering, such as tolerances and thicknesses of mechanical parts. The thou is a very small unit suitable for applications requiring high accuracy.
Chain (ch) equals 66 feet or 20.1168 meters (1 ch = 66 ft = 20.1168 m). It is primarily used to measure land area, especially in surveying and cadastral mapping. Historically, the chain was widely used in agriculture and land measurement.
