Convert meter to picometer
Meter
The metre (Commonwealth spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μετρούν, "measure") is the base unit of length in the International System of Units (SI). The SI unit symbol is m. The metre is defined as the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition was adopted.
Picometer
The picometre (SI symbol: pm) is a unit of length equal to one trillionth of a metre (1×10⁻¹² m), derived from the SI base unit metre using the prefix pico-. It is widely used in chemistry and atomic physics to express atomic radii, bond lengths, and the wavelengths of X-rays. For example, a typical covalent bond length is on the order of 100–200 picometres.
