Quectomole (qmole) – Definition, Conversion & Uses | ChangeUnit
The quectomole (symbol: qmole) is an SI unit of amount of substance equal to 10-30 mole. It uses the SI prefix quecto-, one of the newest metric prefixes introduced in 2022 by the General Conference on Weights and Measures (CGPM). The quectomole provides a convenient way to express extraordinarily small quantities of matter in advanced scientific applications.
What Is a Quectomole?
A quectomole is a unit of amount of substance equal to 10-30 mole. Like other SI multiples and submultiples, it uses a standard metric prefix to simplify the representation of very small values.
The quectomole is useful when working with extremely small numbers of particles, molecules, or atoms where larger units would produce inconvenient decimal values.
History of the Quectomole
The prefix quecto- was officially adopted by the 27th General Conference on Weights and Measures (CGPM) in 2022. It was introduced together with the prefix ronto- to extend the SI prefix system and accommodate the growing need for standardized names for extremely small quantities in science and technology.
Current Uses of the Quectomole
The quectomole is primarily used in advanced scientific research, including analytical chemistry, nanotechnology, molecular biology, quantum science, and particle physics. Although rarely encountered in everyday laboratory work, it provides an internationally standardized way to express extremely small amounts of substance.
Quectomole Conversion
One quectomole is equal to:
- 1 × 10-30 mole (mol)
- 0.001 rontomole (rmol)
- 0.000001 yoctomole (ymol)
- 1 × 10-12 attomole (amol)
