Scientific notation calculator
Write a number in the form coefficient × 10^exponent.
Formula
x ≈ coefficient × 10^exponent; coefficient rounded to 12 decimals
Power of ten ≈ (3)+floor((1.234)÷10) · Coefficient ≈ (1,234)÷abs((1,234))×(1.234)÷10^floor((1.234)÷10)
How to use
- Enter a number, such as 1234 or 4.5e-3.
- Read the coefficient and exponent.
- Combine them as coefficient × 10^exponent.
Examples
- 123400 = 1.234 ×10^5.
- 0.0045 = 4.5 ×10^−3.
Frequently asked questions
What range does the coefficient use?
For nonzero values, its magnitude is at least 1 and below 10 after rounding and normalization.
How is zero written?
This tool uses coefficient 0 and exponent 0.
What does a negative exponent mean?
The magnitude is below one: 4.5×10^−3 =0.0045.
