Scientific Notation Calculator
The Scientific Notation Calculator helps you quickly convert any number into scientific notation, making it easier to work with very large or very small values in mathematics, physics, and engineering.
Scientific Notation Calculator – Convert Numbers Online Easily
Intro
The Scientific Notation Calculator online is a powerful tool designed to make working with very large or very small numbers simple. Scientific notation is commonly used in mathematics, science, engineering, and finance to express values that would otherwise be difficult to read and calculate manually.
For example, instead of writing 0.00000056, scientific notation represents it as 5.6 × 10⁻⁷. Similarly, a huge number like 5600000000 becomes 5.6 × 10⁹. This makes calculations much easier, especially in fields like physics, astronomy, and chemistry.
With the Scientific Notation Calculator online, anyone can convert, multiply, divide, add, and subtract numbers in scientific notation instantly and accurately.
Formula / Working
The tool works based on the rules of scientific notation:
- Basic Scientific Notation Formula:
N=a×10nN = a \times 10^nN=a×10n
Where:
- aaa = a number between 1 and 10
- nnn = an integer exponent (positive or negative)
- Converting a Large Number:
Move the decimal point to the left until only one non-zero digit remains on the left. Count how many places you moved → this becomes the exponent nnn.
Example: 5600000000=5.6×1095600000000 = 5.6 \times 10^95600000000=5.6×109
- Converting a Small Number:
Move the decimal point to the right until one non-zero digit is left on the left. Count the moves → exponent nnn becomes negative.
Example: 0.00000056=5.6×10−70.00000056 = 5.6 \times 10^{-7}0.00000056=5.6×10−7
- Operations with Scientific Notation:
- Multiplication: (a×10m)(b×10n)=(a×b)×10m+n(a \times 10^m)(b \times 10^n) = (a \times b) \times 10^{m+n}(a×10m)(b×10n)=(a×b)×10m+n
- Division: (a×10m)÷(b×10n)=(a÷b)×10m−n(a \times 10^m) \div (b \times 10^n) = (a \div b) \times 10^{m-n}(a×10m)÷(b×10n)=(a÷b)×10m−n
- Addition/Subtraction: Convert to the same power of 10 before adding or subtracting.

Examples
Example 1: Large Number Conversion
Convert 98,000,000 to scientific notation.
- Step 1: Move decimal 7 places left → 9.8
- Step 2: Exponent = 7
- Result:
98,000,000=9.8×10798,000,000 = 9.8 \times 10^798,000,000=9.8×107
Example 2: Small Number Conversion
Convert 0.0000345 to scientific notation.
- Step 1: Move decimal 5 places right → 3.45
- Step 2: Exponent = –5
- Result:
0.0000345=3.45×10−50.0000345 = 3.45 \times 10^{-5}0.0000345=3.45×10−5
Example 3: Multiplication in Scientific Notation
Multiply (3×104)(2×103)(3 \times 10^4)(2 \times 10^3)(3×104)(2×103).
- Multiply coefficients: 3×2=63 \times 2 = 63×2=6
- Add exponents: 104+3=10710^{4+3} = 10^7104+3=107
- Result:
(3×104)(2×103)=6×107(3 \times 10^4)(2 \times 10^3) = 6 \times 10^7(3×104)(2×103)=6×107
