Amperes-hour (Ah) and Coulombs (C) are both units used to measure electric charge. While amperes-hour is typically used to describe the capacity of batteries or the total charge transferred over time, Coulombs measure the actual quantity of charge.
Understanding the Conversion:
- 1 Ampere-hour (Ah) is equal to the charge transferred by a current of 1 ampere flowing for 1 hour.
- 1 Ampere-hour is equivalent to 3,600 Coulombs because 1 hour is equal to 3,600 seconds, and Coulombs can be calculated by multiplying current (in amperes) by time (in seconds).
Conversion Formula:
To convert Ampere-hours (Ah) to Coulombs (C), you can use the formula:
Example Calculation:
If you have a battery with a charge of 2 Ah, the charge in Coulombs can be calculated as:
This means a 2 Ah charge is equivalent to 7,200 Coulombs of electric charge.
Why Use This Conversion?
This conversion is useful in various contexts such as battery capacity measurement, electrical circuit analysis, and understanding charge flow in electrical systems. Coulombs provide a precise way to quantify charge, whereas Ampere-hours are more commonly used in practical applications like battery ratings.
