Scientific notation to decimal
Type a value in × 10ⁿ to get it in decimal instantly.
1,234,000decimal
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: decimal to × 10ⁿ
What it means
How big is that?

The math
How to convert × 10ⁿ to decimal
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 × 10⁶ × 10ⁿ = 1,234,000 decimal.
