Originally created as a set of Unit Converter Javascript Pages that you can see in Chris’s archive, Hammerhead unit converter Java program lets you convert between many units. It was first converted from the Javascript pages to a Java Applet. Most browsers no longer allow Java applets to run in them, but we created a version that is a standalone Java program.
Both the Hammerhead Java applet and Java program can convert length (distance), area, density, power, viscosity, pressure, energy, force, mass, volume, acceleration, temperature, time and volume.
Java programs like this can easily run on Windows and Linux. It is a simple program in a JAR file that doesn’t need to be installed. We may look into installable versions that could be included in Linux repos like Flatpack, to make it easier to add to computers. We could also make it into a mobile app for Android and iOS, but it would require rebuilding the graphical interface. Chris has been thinking about since 2013, so we may need motivation to do it.
