Today I started a converter for Imperial lengths to Metric lengths. The user will be able to insert a length, select an imperial unit and a metric unit, and the page will display the conversion. I focused on the HTML and CSS today, getting the page to look about how I want it.
Tomorrow I will work on the JavaScript for the conversion. I plan to use a function to detect the imperial and metric units. At the moment I am only planning for length conversions, but I might expand that later on.
