Deciview Calculator

Introduction : This calculator calculates the value of the deciview (dV), a unitless value. In this calculator, you have one input value:
  1. visual range (vr), in kilometers (km)

The algorithm for the the calculation is:

dV = 10 ln (391 km/vr)

where vr is the visual range value.
