Have you ever needed to convert feet to picometers? Zeptometers to Siriometers? Megaparsecs to yoctometers? There are so many awesome units that your average internet converter doesn't have! Right now only lengths are supported, but I'll be adding other measures in the near future and yes, you have to click the length button even though its the only option right now.
This project wouldn't be possible without Zro716 's Infinite Precision Calculator https://scratch.mit.edu/projects/51335450/ ! If you find any mistakes or missing (supported) units, please comment! WARNING: Don't use the google converter to convert parsecs to light years, the conversion is incorrect. UPDATE: it appears their is a very slight error in the calculator, but it is very small.
