resisting force formula. OpenUV - Global UV Index API - Knowledge Base 9. Apply the scale. From the calculated value, read a UV Index scale and adhere to the warnings associated with the value (yikes, 15 is very danger... This value can be used to determine what microorganisms you would expect to kill using independent research data. You can also calculate heat index using the heat index formula which is: HI = c1 + c2T + c3R + c4TR + c5T2 + c6R2 + c7T2R + c8TR2 + c9T2R2. Calculator We can transform the formula (3) excluding the extinction coefficient k, and measure the reflection coefficient R at an angle of incidence close to the normal in the wavelength range of (200 – 720) nm with a step of 1 nm.
