Convert numbers to scientific, E-, and engineering notation.
🔬 Scientific notation expresses very large/small numbers compactly. 6.022 × 10²³ is Avogadro's number.
Scientific notation expresses very large or small numbers as a mantissa times a power of 10 — like 6.022 × 10²³ for Avogadro's number, or 1.6 × 10⁻¹⁹ for an electron's charge. This tool converts to scientific, E-, and engineering notation.
The Scientific Notation Converter converts scientific notationfrom one unit to another using the exact internationally defined conversion factors. Type a value, choose your source and target units, and the converted result is shown instantly — no waiting, no page reload.
Manual conversion is error-prone because it means memorizing ratios (how many feet in a meter, how many pints in a liter). This tool removes that friction: the conversion factor is built in, and the math is done to full precision with no rounding until the final displayed number.
Common uses: people reach for this tool when they need to look up a convert number to scientific notation, scientific to engineering notation, e notation converter, or standard form to scientific.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
The Scientific Notation Converter is based on the following formula:
N = a × 10^n (1 ≤ |a| < 10)
Variables: N = The number being converted a = Mantissa, with 1 ≤ |a| < 10 n = Integer exponent, the order of magnitude 10^n = Power-of-ten scale factor
Scientific notation writes a number as a mantissa a times a power of ten. The exponent n shows the order of magnitude; converting just moves the decimal point.
Worked example: Step 1: N = 47,300. Move the decimal 4 places left: a = 4.73. Step 2: n = 4, so N = 4.73 × 10^4. Step 3: Reverse direction: 0.0021 → move the decimal 3 places right: a = 2.1, n = −3. Result: 47,300 = 4.73 × 10^4 and 0.0021 = 2.1 × 10^−3.
