The lowest altitude of the visible portion of the cloud is the cloud base. Its height can be measured using a ceilometer. Use our online cloud base altitude calculator which helps you to calculate the cloud base. Just enter the values of temperature and dew point in Fahrenheit to know the result of cloud altitude.
Find the cloud base altitude if the air temperature is 69 F and the dew point is 6 F?
Cloud Base Altitude = ( ( 69 - 6 ) / 4.4 ) * 1000 )
