I am a chemical engineer by education. In my career I have come in contact with a lot of laboratory technicians, manufacturing technicians, boiler mechanics, electricians, etc. I wish to address some of their needs in this website. Eventually, I wish to form an organization for this specific purpose. The most important thing is to ensure high quality calculators with a consistent presentation format.
