What Is This Tool?
This unit converter helps transform radiation exposure measurements from the SI unit coulomb per kilogram (C/kg) to the derived unit microcoulomb per kilogram (µC/kg). It supports calibration, regulatory, and measurement tasks involving ionizing photon exposure levels in air.
How to Use This Tool?
-
Enter the value in coulomb per kilogram (C/kg) you want to convert.
-
Select 'coulomb/kilogram [C/kg]' as the input unit.
-
Choose 'microcoulomb/kilogram [µC/kg]' as the output unit.
-
Click the convert button to get the result in microcoulombs per kilogram.
-
Use the result for calibration, measurement documentation, or regulatory purposes.
Key Features
-
Converts radiation exposure from coulomb/kilogram to microcoulomb/kilogram.
-
Supports calibration and regulatory compliance in medical and industrial radiology.
-
Provides examples for practical understanding.
-
Easy to use with step-by-step conversion process.
-
Browser-based tool suitable for quick conversions.
Examples
-
0.005 C/kg equals 5,000 µC/kg after conversion.
-
2 C/kg converts to 2,000,000 µC/kg using the conversion factor.
-
Multiply the C/kg value by 1,000,000 to obtain the µC/kg equivalent.
Common Use Cases
-
Calibrating ionization chambers and radiography survey meters.
-
Performing quality control on photon beam exposure in medical imaging tests.
-
Regulatory and workplace monitoring of X-ray, CT, and gamma-ray exposure levels.
-
Converting older exposure data measured in roentgens to SI units.
-
Documenting radiation protection levels for safety compliance.
Tips & Best Practices
-
Ensure measurement conditions like temperature and pressure are considered since they affect ionization.
-
Use this conversion specifically for ionization in dry air; other media require different approaches.
-
Regularly calibrate instruments to maintain conversion accuracy.
-
Apply correct unit notation for clear communication in reports.
-
Verify values especially at micro-unit scale to minimize errors.
Limitations
-
Conversion is valid only for ionization measurements in dry air.
-
Environmental factors such as temperature and pressure can influence readings.
-
Precision depends on calibration quality and measurement methods.
-
Inapplicable for absorbed dose measurement units or other media besides air.
-
Small inaccuracies in instrumentation may affect micro-level conversions.
Frequently Asked Questions
-
What does coulomb per kilogram measure?
-
It measures ionizing radiation exposure as the electric charge of one sign produced by photons in a unit mass of dry air.
-
Why convert from coulomb/kilogram to microcoulomb/kilogram?
-
Converting to microcoulomb/kilogram expresses radiation exposure in smaller, practical units useful for calibration, regulatory reporting, and precise measurements.
-
Can this conversion be used for media other than dry air?
-
No, this conversion specifically applies to ionization produced in dry air and should not be extrapolated to other media.
Key Terminology

Coulomb per kilogram [C/kg]
-
An SI unit quantifying ionizing radiation exposure as the electric charge generated in one kilogram of dry air.
-
Microcoulomb per kilogram [µC/kg]
-
An SI-derived unit representing a millionth of a coulomb per kilogram used to express radiation exposure.
-
Radiation Exposure
-
