Metric Prefixes Converter
Convert between SI metric prefixes from quetta (10³⁰) down to quecto (10⁻³⁰). Multiply a base unit by the prefix factor to get the scaled unit.

Frequently asked questions
What units does this metric prefixes converter support?
It supports 25 units: Quetta (Q) (Q), Ronna (R) (R), Yotta (Y) (Y), Zetta (Z) (Z), Exa (E) (E), Peta (P) (P), Tera (T) (T), Giga (G) (G), Mega (M) (M), Kilo (k) (k), Hecto (h) (h), Deka (da) (da), None (—), Deci (d) (d), Centi (c) (c), Milli (m) (m), Micro (µ) (µ), Nano (n) (n), Pico (p) (p), Femto (f) (f), Atto (a) (a), Zepto (z) (z), Yocto (y) (y), Ronto (r) (r), Quecto (q) (q).
What is the base unit of metric prefixes?
The SI reference unit is the unit (1). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
