Convert between ordinary decimal numbers and scientific notation in both directions. Scientific notation, sometimes called standard form, writes a number as a coefficient between one and ten multiplied by a power of ten, which makes very large and very small quantities compact and easy to compare. This tool takes any number you type, whether it is a plain decimal like 0.00042 or an expression like 6.022e23, and shows you the scientific form, the E notation used by calculators and code, and the fully expanded decimal. That makes it handy for chemistry, physics, astronomy and engineering where quantities span dozens of orders of magnitude. Type a value and every representation updates live. All calculation happens in your browser, so nothing is uploaded and it works offline.
