1 mw/cm2 X 1 s = 1 mj/cm2 ( One milliwatt / 1 square cm X 1 second = 1 mm focal/cm2) UV energy unit conversion formula is as follows: energy units: joule ( J） Intensity of energy units: J/m2, mJ/cm2, the light energy 1 joule per unit area ( J) (= 1 n/m = 1 watt W) Per second ( S) 1J/cm² = 1000mJ/ cm² = 1000000uJ/ cm². The scale was developed by Canadian scientists in 1992, then … UV calculator: calculate your uv index of your region - NIVEA And the power unit: E = W * t. 1 W = 103 mW (milliwatts) = 106 uW (microwatts) The above is the conversion rate of the UV energy meter light energy unit, UV intensity unit, power unit and their relationship! Bacteria. 31.8) into the ” Wavelength of Absorption peak (in … According to the FDA, the use of a sunscreen with an SPF of 15 or above, combined with other measures, such as wearing sunglasses and avoiding the midday sun, can help prevent. How is a UV Index calculated? - Earth Science Stack Exchange UV Absolute measurement. Lamp intensity is a measure of how much light is produced by the lamp per unit of lamp surface area. How to calculate refractive index from Uv visible spectrum? These precautions help you avoid sunburn in the short term and skin cancer in the long term. There are various recommendations for sun protection of the skin for each level. How do I calculate SUVA (specific ultraviolet absorbance) from a … 7. Choose the scenario. To continue the example we are doing, lets choose an elevation of 5 kilometers (which is the elevation of La Rinconada, Per... SEARCH LOCAL UV INDEX. resisting force formula. uv index calculation
