Tc calculator

Beautiful effort

I am a old Linux user and this Tc is a great example of BC calc I don't know why it is not more widely known. I will become a subscriber in the near future (money issues) . Just for your enjoyment if you like calculating languages , look up Frink at Frinkorg , you will enjoy it
Example : you can type 12.5 Ktons of TNT / (6 years + 9 months) --> horsepower and it will give you an answer. and if you use frink on Android it can speak the answer in Mandarin and possible even Slovak. LOL
