We'd like to show you some TopCode coding examples....


There are lots of calculators on the web and lots of sites with lists of formulae. TopCode has put the two together so you can calculate the answer to a mathematical problem without knowing the formula. If your problem is not listed, let us know.

How to use the calculator:

  • Find a form for your maths problem...
  • Enter the data...
  • Click 'Calculate'!


Convert any unit into another, even some units you may not have heard of.

BMI calculator

Calculate your BMI to see your weight classification. It might be the time to diet!


TopCode's digitiser tool helps you create a polyline lat/long coordinate string.
