Alfred unit converter is a really fast smart calculator for Alfred with support for unit conversions to make it a bit comparable to the Google Calculator and Wolfram Alpha. If new units and/or other names for units should be added please let me know by creating an issue at:https://github.com/WoLpH/alfred-converter/issues Example queries Downloadable from Packal: http://www.packal.org/workflow/unit-converter 1m in cm # Just a simple conversion 2^30 byte # Using powers before conversion 5' # Converting units with special characters 20" # Like above 5 * cos(pi + 2) # Executing mathematical functions 5 * pi + 2 mm in m # Mathematical constants with unit conversion 1 * cos(pi/2) - sin(pi^2) # More advanced mathematical expressions ln(e^10) # Testing the ln(x) alias of log _e(x) log(e^10) # The normal log method 5+3^2" in mm # Testing math with unit conversion 1 + 2 / 3 * 4) mm^2 in cm^2 # Unbalanced paranthesis with unit conversion ((1 + 2 / 3 * 4) mm^2 in cm^2 # Unbalanced paranthesis the other way inf - inf # Not actually possible, but we backtrack to "inf" The list of units and conversions was downloaded from:http://w3.energistics.org/uom/poscUnits22.xml It returns results within 50 milliseconds making it fast enough to use the results instead of the standard alfred calculator. It supports more too Note: the parser automatically works when you start with a number or a ".". For all other cases (functions for example) it's best to just use "=". For example: "=ln(e^5)"
