Campbell Stokes Recorder: measures sunshine. This unit of measurement, expressed as grams of water vapor per kilogram of air (g/kg), does not change depending on temperature or atmospheric pressure. Convert torque values and units of measure to meet your needs! The 7 Base SI Units of Measurement Defined by Fundamental Constants. 7 8 9. These sunshine recorders (also known as Campbell-Stokes recorders), measure the number of hours in the day during which the sunshine is above a certain level (typically 200 mW/cm 2). A 12 month comparison between the Campbell-Stokes and the Instromet sensor (then known as the R&D sunshine sensor) was published in Weather in 1997 (‘Trialling of an inexpensive electronic sunshine sensor, June 1995 to May 1996’ by C G Roberts, Weather, 52, pp 371-377, December 1997). For example, a length is a physical quantity.The metre is a unit of length that represents a definite predetermined length.
