Unit Explanations
GrayGy
Source UnitThe gray (Gy) is the SI derived unit of absorbed dose of ionizing radiation, defined as the absorption of one joule of radiation energy by one kilogram of matter. It quantifies the amount of energy deposited by radiation in a specified mass of material, which in biological contexts is often human tissue. The gray is crucial in assessing radiation exposure and its potential biological effects, and it serves as a fundamental unit in radiation safety and protection protocols.
Current Use
The gray is widely used in medical fields, particularly in radiation therapy for cancer treatment, where precise dosages are critical for effective treatment while minimizing damage to surrounding healthy tissue. It is also employed in radiological assessments, nuclear power, and safety protocols for radiation workers. Various international organizations, including the International Atomic Energy Agency (IAEA), utilize the gray for consistent communication regarding radiation exposure levels.
Fun Fact
The gray is equivalent to 100 rad, an older unit of absorbed dose.
Millicoulomb KilogrammC kg
Target UnitThe millicoulomb (mC) is a unit of electric charge in the International System of Units (SI) and represents one-thousandth (1/1000) of a coulomb (C). It is commonly used in various scientific and engineering applications where smaller quantities of electric charge are of interest. The kilogram (kg) is the base unit of mass in the SI system, and it is defined as being equal to the mass of the International Prototype of the Kilogram. When combined, millicoulomb kilogram (mC kg) could denote a specific charge associated with a mass, often in contexts such as radiation measurements where electric charge and mass interact.
Current Use
Millicoulomb kilograms are frequently used in fields such as radiation therapy, where precise measurements of charge associated with particles are critical. This unit allows researchers to quantify the electric charge of radiation particles relative to their mass, aiding in the understanding of their interactions with matter. It is also relevant in electrochemistry for determining the charge transferred during chemical reactions and in various industrial processes involving electric charge.
Fun Fact
The millicoulomb is often used in nuclear medicine for precise dosage calculations.

Gray
radiation • SI Unit
Definition
The gray (Gy) is the SI derived unit of absorbed dose of ionizing radiation, defined as the absorption of one joule of radiation energy by one kilogram of matter. It quantifies the amount of energy deposited by radiation in a specified mass of material, which in biological contexts is often human tissue. The gray is crucial in assessing radiation exposure and its potential biological effects, and it serves as a fundamental unit in radiation safety and protection protocols.
History & Origin
The gray was introduced in 1975 by the International System of Units (SI) as the unit of absorbed dose to provide a standardized measurement for radiation exposure. Its creation was a response to the need for a unified system that could facilitate consistency in scientific research and practical applications in radiology, nuclear medicine, and radiation therapy.
Etymology: The unit is named after the British physicist Louis Harold Gray, who made significant contributions to the field of radiation therapy and the study of radiation's effects on biological tissue.
Current Use

Millicoulomb Kilogram
radiation • Non-SI
Definition
The millicoulomb (mC) is a unit of electric charge in the International System of Units (SI) and represents one-thousandth (1/1000) of a coulomb (C). It is commonly used in various scientific and engineering applications where smaller quantities of electric charge are of interest. The kilogram (kg) is the base unit of mass in the SI system, and it is defined as being equal to the mass of the International Prototype of the Kilogram. When combined, millicoulomb kilogram (mC kg) could denote a specific charge associated with a mass, often in contexts such as radiation measurements where electric charge and mass interact.
History & Origin
The concept of electric charge dates back to the early experiments in electricity conducted by pioneers like Benjamin Franklin in the 18th century. The coulomb was named after Charles-Augustin de Coulomb, who formulated Coulomb's law in 1785, defining the force between charged objects. The millisi unit was introduced to allow more manageable measurements of charge, especially in applications like electrochemistry and radiation. The kilogram, established in 1795, became the standard unit of mass, leading to the modern conventions we use today.
Etymology: The term 'coulomb' is derived from the name of the French physicist Charles-Augustin de Coulomb, while 'milli' originates from the Latin word 'mille,' meaning one thousand.
Current Use
Millicoulomb kilograms are frequently used in fields such as radiation therapy, where precise measurements of charge associated with particles are critical. This unit allows researchers to quantify the electric charge of radiation particles relative to their mass, aiding in the understanding of their interactions with matter. It is also relevant in electrochemistry for determining the charge transferred during chemical reactions and in various industrial processes involving electric charge.
💡 Fun Facts
- •The millicoulomb is often used in nuclear medicine for precise dosage calculations.
- •Coulomb's law is fundamental in understanding electrostatic interactions and is taught in physics courses worldwide.
- •The kilogram was once defined by a physical object, the International Prototype of the Kilogram, until it was redefined using fundamental constants.
