What is Scientific Notation?

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in standard decimal form. It is commonly used in science, engineering, and mathematics.

Format Examples

• Large numbers: 1,234,567 = 1.234567 × 10⁶
• Small numbers: 0.000456 = 4.56 × 10^-4
• Scientific input: You can enter 1.23e6 or 1.23E6 for 1.23 × 10⁶
• Negative exponents: Use 1.23e-4 for 1.23 × 10^-4

Key Features

• Convert from standard form to scientific notation
• Convert from scientific notation to standard form
• Displays the exponent separately for clarity
• Handles both very large and very small numbers
• Supports multiple input formats (decimal, exponential, e-notation)

Tips for Accurate Conversions

• Ensure your number is valid (no letters except 'e' or 'E' for exponents)
• Use decimal points correctly (e.g., 1.23 not 1,23)
• For scientific notation input, use 'e' or 'E' to denote the exponent
• The calculator preserves significant figures from your input
