H = the RMS magnetic field strength in amperes per meter. [6] The above equation yields units of W/m 2. In the USA the units of mW/cm 2, are more often used when making surveys. One mW/cm 2 is the same power density as 10 W/m 2. The following equation can be used to obtain these units directly: [6] Pd = 0.1 × E × H mW/cm 2
L-1 Standards and Technology (LASP) designed and built the system, completed in 2008. It was calibrated for optical power against the NIST Primary Optical Watt Radiometer, a cryogenic radiometer that maintains the NIST radiant power scale to an uncertainty of 0.02% (1σ). As of 2011 TRF was the only facility that approached the desired <0.01% ...
Currently, there is over 1 million square meters of solar thermal panels [15] installed in Mexico, while in 2005, there were 115,000 square meters of solar PV (photo-voltaic). It is expected that in 2012 there will be 1.8 million square meters of installed solar thermal panels. [15]

More generally encountered is the traditional unit of μS/cm. The commonly used standard cell has a width of 1 cm, and thus for very pure water in equilibrium with air would have a resistance of about 10 6 ohms, known as a megohm. Ultra-pure water could achieve 18 megohms or more. Thus in the past, megohm-cm was used, sometimes abbreviated to ...
