Decimal to scientific notation
Type a value in decimal to get it in × 10ⁿ instantly.
1.234 × 10⁶× 10ⁿ
That's 1.23× as big as a million, while a billion is 810× bigger. That number has 7 digits before the decimal point.
Convert the other way: × 10ⁿ to decimal
What it means
How big is that?

The math
How to convert decimal to × 10ⁿ
There is nothing to multiply: the same number is written with the decimal point moved and the moves counted as a power of ten. Engineering notation keeps that power a multiple of three.
Example: 1,234,000 decimal = 1.234 × 10⁶ × 10ⁿ.
