Revisions in the definition of the meter are intended to achieve greater precision.
The modern definition of a meter is based on the speed of light in a vacuum, with the wavelength of the orange-red emission line of krypton-86 equaling 1,064,380.046 nm. This particular wavelength corresponds to a specific frequency that is used to define the meter in the International System of Units (SI).
In the SI measurement system, a meter is a "base unit". However, the definition relies on the prior definition of the second.
