Engineering Notation Calculator
Write a number with a power of ten divisible by three.
Formula
x ≈ c × 10ⁿ; n = 3k; 1 ≤ |c| < 1000 for x ≠ 0.
Exponent ≈ (3)+3×floor((74)÷1000) · Coefficient ≈ (74,000)÷abs((74,000))×(74)÷10^(3×floor((74)÷1000))
How to use
- Enter a number.
- Read the coefficient and exponent.
- Combine them as c × 10ⁿ.
Examples
- 74000 = 74 × 10³.
Frequently asked questions
How is this different from scientific notation?
The exponent must be a multiple of three; the coefficient can reach almost 1000.
How is zero shown?
As 0 × 10⁰.
How much rounding is used?
The coefficient is rounded to nine decimal places, then normalized.
