Reference Tools
Sometimes you just need the table: which character is ASCII 65, what is the atomic mass of iron, what is 7 times 8. The reference tools put these lookup tables one click away with instant search, so there is no scrolling through PDFs. Small but handy — and like everything here, they run entirely in your browser.
