Convert lengths between different units like meters, feet, kilometers, and astronomical distances.
Meter (m) - The base unit of length in the International System of Units (SI). Defined as the distance light travels in 1/299,792,458 of a second.
Centimeter (cm) - 1/100th of a meter. Commonly used for measuring smaller distances.
Millimeter (mm) - 1/1000th of a meter. Used for precise measurements.
Micrometer (μm) - 1/1000th of a millimeter. Also known as a micron.
Nanometer (nm) - 1/1,000,000th of a meter. Used in microscopy and nanotechnology.
Inch (in) - Defined as exactly 2.54 centimeters. Used primarily in the United States.
Foot (ft) - 12 inches. Commonly used for measuring height and distance.
Yard (yd) - 3 feet. Used in sports and fabric measurements.
Astronomical Unit (AU) - The average distance between Earth and the Sun, about 150 million kilometers.
Light-year (ly) - The distance light travels in one year, about 9.46 trillion kilometers.
Parsec (pc) - About 3.26 light-years. Used in astronomy to measure vast distances.
Kiloparsec (kpc) - 1,000 parsecs. Used for measuring distances between galaxies.
