This App calculates numbers with physical units. The result for "10km/30min" will be in units of velocity, and the conversion to equivalent units is possible (m/s, mi/h, ...). Physics constants (c, e, planck's constant (hbar) ...), greek symbols, as well as common mathematical functions (sin(), sqrt(), ...) are supported. The result is formatted in scientific form and the whole calculation expression can be copied (Ctrl-C) to any other application.
