Scientific Notation Converter

Sobre esta ferramenta

Enter any number — from subatomic scale (10⁻³⁵) to cosmological scale (10⁸⁶) — and instantly see it expressed in four equivalent notations: standard decimal, scientific notation (coefficient × 10^exponent), engineering notation (exponent restricted to multiples of 3, matching SI prefixes), and E-notation (1.23E6). Round the result to a chosen number of significant figures. Multiply or divide two numbers given in scientific notation directly, with the result shown in all four forms. A curated reference table of real-world quantities — atom radius, wavelength of visible light, Earth's mass, distance to the nearest star, number of atoms in a mole — provides context for extreme values.

Como usar

1. 1 Type any number (e.g. 0.0000123 or 45600000) into the input field.
2. 2 Instantly see the scientific, engineering, E-notation, and standard forms.
3. 3 Use the 'Significant Figures' slider to round the coefficient.
4. 4 Scroll to the calculator, enter two numbers and choose × or ÷.
5. 5 Click 'Calculate' to see the product or quotient in all four notations.
6. 6 Check the reference table for real-world examples at extreme scales.
