The classic Calculator has been replaced with a modern version of Calculator in Windows 10. The new Calculator app in Windows 10 sports a clean user interface and works great on touch devices as well.
In addition to the standard mode that you see by default upon launching the Calculator app with default settings, programmer and scientific modes are also available in the Calculator app. Besides that, the Calculator app includes a converter as well. The converter feature supports volume, length, energy, temperature, weight and mass, angle, pressure, data, time, power, area, and speed.
