SI Prefixes Converter

Our SI Prefixes Converter provides accurate conversions between different metric prefixes used in scientific notation. Whether you're working with large values like tera and giga, or small values like nano and pico, this tool delivers precise results instantly.

Supported Prefix Categories:

  • Large Prefixes: Tera (10¹²), Giga (10⁹), Mega (10⁶), Kilo (10³)
  • Base Unit: Base (10⁰) - no prefix
  • Small Prefixes: Milli (10⁻³), Micro (10⁻⁶), Nano (10⁻⁹), Pico (10⁻¹²)
  • Extreme Prefixes: Peta (10¹⁵), Femto (10⁻¹⁵), Atto (10⁻¹⁸), Zepto (10⁻²¹)

Common Conversions:

  • 1 kilometer = 1,000 meters = 10³ meters
  • 1 megabyte = 1,000,000 bytes = 10⁶ bytes
  • 1 millimeter = 0.001 meters = 10⁻³ meters
  • 1 microsecond = 0.000001 seconds = 10⁻⁶ seconds

How to Use:

  1. Enter the value you want to convert in the input field
  2. Select the source prefix from the "From" dropdown
  3. Select the target prefix from the "To" dropdown
  4. View the converted result instantly
  5. Use the swap button to quickly reverse the conversion

Applications:

This prefixes converter is essential for scientists, engineers, students, researchers, and anyone working with scientific notation. It's particularly useful for physics, chemistry, engineering, computer science, and any field that requires working with very large or very small numbers.
