The speed of light, denoted as cc, is a fundamental physical constant representing the speed at which light propagates through a vacuum. In the International System of Units (SI), its exact value is defined as a ..more definition+
In relation to the base unit of [speed] => (meters per second), 1 Speed Of Light (c) is equal to 299792458 meters-per-second, while 1 Cosmic Velocity First (v1) = 7900 meters-per-second.| 1 Speed Of Light | to common speed units |
