• Sum of Masses: this adds two masses
• Difference of Masses: this computes the difference in two masses
• Multiple of a Mass: this multiplies a mass by a real number
• Mass Produced: amount of mass processed (produced or consumed) over time based on a production rate.
• Unit Conversions:  this converts the input mass or weight into:
  • (mg) milligrams
  • (g) grams
  • (kg) kilograms
  • (t) metric ton
  • (oz) ounces
  • (lb) pounds
  • (ton_us) U.S. tons [short ton]
  • (ton_uk) U.K. tons [long ton]
  • (me) mass of electron at rest
  • (u) atomic mass unit
  • (gr) grain
  • (ct) carat
  • (dwt) penny weight
  • troy ounce
