Astronomy carries ordinary quantities to extraordinary scales. Wondering what your weight would be on another planet, how many kilometers a light-year equals or the magnification of a telescope are questions for anyone interested in the sky. The tools in this category make these calculations accessible.
With tools such as planet weight, light-year conversion and telescope magnification calculation, you enter your values and instantly see the result. It offers students a way to enrich projects, and stargazers a fun way to make the scales of the universe tangible.
