The following table provides conversions for wavelength (from frequency), VSWR (from forward and reflected power) and various other useful conversions. Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the elements. The amount of UVAB light intensity is displayed in mW/CM2 (how much energy is concentrated per square cm of area). As one person mentioned, you need to take into account beam angle and pattern to make a rough conversion, but you also need to take into account the eye sensitivity at that wavelength. Watt/square meter Unit Conversions » Watt/square meter ↔ W/cm2 Conversion from Power Density units: mW/cm 2 to W/m 2 and μW/cm 2 to mW/m 2. The following table provides conversions for wavelength (from frequency), VSWR (from forward and reflected power) and various other useful conversions.

Iunit (str) – intensity unit (can be ‘counts’, ‘mW/cm2/sr/nm’, etc…). W/m2 watt/square meter Unit Conversions. mW to deciwatt mW to foot pound-force/second mW to yoctowatt mW to erg/second ›› Definition: Milliwatt. RADIS is a fast line-by-line code for high resolution infrared molecular spectra (emission / absorption, equilibrium / nonequilibrium). As other members have indicated, your meter will monitor a specific portion of the "energy spectrum" - google that for an eye … The power P (dBm) in dBm is equal to 10 times the base 10 logarithm of the power P (mW) in milliwatts (mW) divided by 1 milliwatt (mW): P (dBm) = 10 ⋅ log 10 ( P (mW) / 1mW) So, 1mW = 0dBm. Example: 1 mW/m 2 = (0.001 * 377) 1/2 V/m = 0.6 V/m. Molecular Weight Calculator.
