Amici Businessware Calculator (ABCalc) is a very simple calculator program for converting between different units for temperature, pressure, energy, volume, volumetric flow, mass, length, time, and specific weight.  It was originally written in 2003 as a quick tool for common calculations we do in Amici Water Systems.


  • Unit Conversion for
    • Temperature (Celsius, Fahrenheit, Kelvin, Rankine)
    • Pressure (Bar, Millibar, Newton/Meter2, Pascal, Hectopascal, Dyne/cm2, Atmosphere, Torr, psi, psf, inch of air, inch of water, water columns)
    • Volume (m3, cm3, cubic inch, cubic feet, cubic yard, gallon US, gallon Eur, ounce fluid)
    • Volumetric Flow (m3/s, cm3/s, l/s, cu ft/s, cu yd/s, gal/s, gal/m, gal/h, gal/d
    • Length (centimeter, decimeter, meter, kilometer, inch, foot, yard, mile)
    • Time (millisecond, second, minute, hour, day, week, month, year)
    • Mass (milligram, centigram, decigram, gram, kilogram, metric ton, long ton, ton, ounce, pound)
    • Energy (kilowatthour, Newtonmeter ), Watthour (wh), Wattsecond (Ws), Calorie (cal), Kilocalorie, Foot pound force, British thermal unit (Btu))
  • Box Volume Calculation
  • Volumetric Flow Calculation
  • Pool Water Volume to Chlorine Mass Requirement for pool water
  • LPG vs Electricity Water Heating cost calculator
