Abstract
Recent frequency and wavelength measurements of a methane stabilized laser yield a value of the speed of light 100 times less uncertain than the previously accepted value. Various possibilities using lasers as radiation sources for a new length standard are discussed. One possibility is to fix the value of the speed of light in the redefinition of the meter.
