🔎 Did you know that…?

A meter is the length of the path that light travels in a vacuum in 1/299,792,458 s.! 🚀

On October 21, 1983, at the 17th General Conference on Weights and Measures, the definition of the length of a meter was changed to the one currently in effect.

Since that year, the official value of the speed of light in a vacuum is exactly 299,792,458 m/s. To celebrate this milestone day, we are celebrating International Fotonics  Day.
