-Added % Grade, Pitch, Slope, Incline, Gradient to the Angle Conversion Calculator *now you can easily convert from % Grade to Degrees & Radians -> (commonly encountered on steep roads) **Note: lower cased unit "tilt" is a shortcut to the built-in Accelerometer ChangeUnits2 Force Calculation Gauge, which calculates Rolling Force due to Gravity in addition to providing % Grade & Angle degrees. ("Accelerometer" as a unit also works) -Updated Temperature Conversion page to accept "deg C", "deg F" & "deg K......( also "ev/kB" for us Nerds :) -Updated Angle Conversion Calculator to accept "rad", "deg" & "° " -> (such as in 45°) -Updated Scientific Constants to include "c" for Speed of Light
