The Distance Light Traveled calculator computes the distance (D) based on the duration of travel (t) and the Speed of Light .

INSTRUCTIONS:  Choose the preferred units and enter the following:

  • (t)   Duration of travel
  • (v)  This is the velocity (travel speed) with a default of 1 c (the speed of light)

Distance Traveled:  The calculator returns the distance (D) in astronomical units or light years.  However, this can be automatically converted to other distance units via the pull-down menu.

The Math / Science

The formula for the distance that light has traveled is:

  D = t•v
