UnitConSI Prefixes
SI prefixes represent powers of ten and make very small or very large values easier to read. They can be applied to many different base units, from meters and watts to bytes and volts. This converter helps move between prefixes without changing the underlying physical quantity. It is useful in science, engineering, computing, and education.

Frequently asked questions
SI prefixes are standardized labels for powers of ten. They help express values more clearly without writing long strings of zeros.
Giga means one billion, or 10⁹. It is commonly used in watts, hertz, and bytes.
Mega means 10⁶ and giga means 10⁹. That makes giga one thousand times larger than mega.
The SI prefix for 10⁻⁹ is nano. It is often used in electronics, materials science, and nanotechnology.
