NOTE: Javascript must be enabled in order to use this calculator. Please note, this a test version page which does not include input range checking, so a valid time will not be returned if temperatue and wind entries are not within the stated valid range. It also runs two different functions (one to lookup the value from a table, one to calculate it using a formula) 10,000 times for execution time testing. Click here for a proper production version. I did not bother with interpolation for the lookup table, as did not seem worthwhile.
