Type any number or equation in the input box and get a result. The default unit will be the one selected from the drop down menu.
It is recommended that you type your units right into the input box for fastest results.
You can type a question in human readable format.
The drop down menu will only be used for numbers that dont have a unit attached to them.
If you try to change the drop down selection when all numbers have a unit assigned to them it will not change.
This is due to the fact that the input box will always override the selection from the drop down items.
