Dude! It’s free and it converts… (Let me take a breath here…) Acceleration, Angle, Area Byte Currency, Current, Energy, Force, Illumination, Inductance, Length Magnitude, Mass, Power, Pressure, Radiation, Temperature, Time, Torque, Volume and Velocity!!!!! But wait, there’s much more control!!!

You can set your preferences for:

Hot key
start at Login
Show icon in dock
Keep app visible in background
Keep app above other apps
Pin app to menubar
Window opacity

How much more do you want for free????? Did I say GRATIS???? Did I say without charge or recompense?
