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.
Microcoulomb KilogramμC kg
Target UnitThe microcoulomb kilogram (μC kg) represents the product of electric charge measured in microcoulombs (μC) and mass measured in kilograms (kg). It quantifies the interaction of charged particles under gravitational influence. In the SI system, the coulomb is the standard unit of electric charge, equivalent to the charge transported by a constant current of one ampere in one second. The microcoulomb is one-millionth of a coulomb, making it suitable for measuring smaller electric charges. The combination with kilograms allows for the analysis of forces acting on charged particles in gravitational fields, providing insights into their behavior in various physical scenarios.
Current Use
Microcoulomb kilograms are used primarily in experimental physics and engineering, particularly in fields involving electrostatics and radiation. They facilitate the calculation of forces acting on charged particles in gravitational fields, which is crucial in understanding particle behavior in accelerators and sensors. Industries such as semiconductor manufacturing, aerospace, and medical imaging utilize the μC kg in applications where precise measurements of charge and mass are vital for safety and efficiency. Countries engaged in advanced research, including the USA, Germany, and Japan, frequently apply this unit in their scientific evaluations.
Fun Fact
The microcoulomb is a preferred unit in many precision applications, including semiconductor technology, due to its manageable size.

Definition
The microcoulomb kilogram (μC kg) represents the product of electric charge measured in microcoulombs (μC) and mass measured in kilograms (kg). It quantifies the interaction of charged particles under gravitational influence. In the SI system, the coulomb is the standard unit of electric charge, equivalent to the charge transported by a constant current of one ampere in one second. The microcoulomb is one-millionth of a coulomb, making it suitable for measuring smaller electric charges. The combination with kilograms allows for the analysis of forces acting on charged particles in gravitational fields, providing insights into their behavior in various physical scenarios.
History & Origin
The concept of electric charge can be traced back to ancient Greece, where Thales of Miletus discovered static electricity by rubbing amber. The formalization of charge measurement occurred in the 19th century with the work of Coulomb, who formulated Coulomb's Law, defining the force between electric charges. The microcoulomb emerged as a practical subunit for electric charge, adopted in various scientific fields to handle small quantities. The kilogram, as a mass unit, has its origins in the metric system established in France in the late 18th century, evolving through several definitions until it was redefined in 2019 based on Planck's constant.
Etymology: The term 'microcoulomb' derives from the Greek prefix 'micro-' meaning one-millionth and 'coulomb', named after Charles-Augustin de Coulomb, a French physicist. 'Kilogram' comes from the French 'kilogramme', with 'kilo-' representing a factor of one thousand and 'gram' derived from the Greek 'gramma', meaning a small weight.
Current Use
Microcoulomb kilograms are used primarily in experimental physics and engineering, particularly in fields involving electrostatics and radiation. They facilitate the calculation of forces acting on charged particles in gravitational fields, which is crucial in understanding particle behavior in accelerators and sensors.
