What Is This Tool?
This tool converts values from ampere-minute [A*min], a unit measuring electric charge over a minute, to millicoulomb [mC], a smaller unit for electric charge. It helps you translate charge measurements into units better suited for detailed engineering or laboratory applications.

-
Click the convert button to see the result immediately
-
Use the conversion result for calculations or reporting in smaller charge units
Key Features
-
Converts charge values from ampere-minute [A*min] to millicoulomb [mC]
-
Uses the exact conversion factor of 1 A·min = 60000 mC
-
Suitable for electrical engineering, electrochemistry, and medical device contexts
-
Browser-based and easy to use with no installation required
-
Provides clear examples to assist understanding
Examples
-
Convert 2 A·min: 2 × 60000 = 120000 mC
-
Convert 0.5 A·min: 0.5 × 60000 = 30000 mC
Common Use Cases
-
Measuring total electric charge during short battery discharge or pulse tests
-
Reporting integrated charge in electrochemical procedures like electroplating
-
Specifying charge in pulsed-power or welding processes over minute intervals
-
Describing charge transferred during capacitor discharges in electronics testing
-
Recording stimulation charge delivered by medical electrical devices
-
Conducting small-scale coulometric or electrochemical lab measurements
Tips & Best Practices
-
Ensure the current remains steady for the entire minute when measuring in ampere-minutes
-
Use this conversion for more granular and precise engineering-scale charge values
-
Double-check the time interval as ampere-minute assumes one full minute of current flow
-
Apply this tool in contexts where smaller charge units like millicoulombs improve clarity
-
Refer to examples to verify correct input and output values
Limitations
-
Assumes steady current for the full one-minute interval, not accounting for transient currents
-
Requires accurate timing to avoid conversion errors due to time measurement discrepancies
-
Does not handle conversions for other charge units beyond ampere-minute and millicoulomb
Frequently Asked Questions
-
What is an ampere-minute (A·min)?
-
An ampere-minute measures the total electric charge transferred by a steady current of one ampere flowing for one minute, equal to 60 coulombs.
-
Why convert ampere-minute to millicoulomb?
-
Converting to millicoulombs provides a smaller, more precise unit for electric charge useful in electronics testing, medical devices, and laboratory measurements.
-
Is this conversion suitable for varying currents?
-
No, the conversion assumes a steady current flowing throughout the minute. For transient or varying currents, more detailed analysis is needed.
Key Terminology
-
Ampere-minute [A*min]
-
A unit of electric charge equal to the charge transferred by a steady current of one ampere flowing for one minute, equivalent to 60 coulombs.
-
Millicoulomb [mC]
-
A unit of electric charge equal to 0.001 coulombs, useful for expressing smaller amounts of charge in electrical systems.
-
Electric Charge
-
A physical quantity representing the amount of electricity transferred or stored in a system, measured in units such as coulombs or its submultiples.
