How is the combine correction calculated in m when the units used are km

[@MasterCivilEngineering]

Thanks for watching dear

[@MasterCivilEngineering]

Combined correction in meter is given as
C = 0.0673d^2
Where d is in Km

[@saurabhjadhav6845]

Cccr is +0.0673 or -0.0673

Thanks for watching Master Civil Engineering

[@MasterCivilEngineering]

Combined correction for curvature and refraction is C = - 0.0673d^2
Where d is distance in Km and C is in m
