Ampere-Minute to Coulomb Converter

Demystifying Electrical Charge Units: Ampere-Minutes and Coulombs

When working with electrical systems, understanding and converting between different units of electrical charge is crucial. The Ampere-Minute to Coulomb Converter is a valuable tool that helps engineers, students, and hobbyists quickly and accurately convert between these two important units of electrical charge.

What is an Ampere-Minute?

An ampere-minute (A·min) is a unit of electrical charge that represents the amount of charge transferred by a steady current of one ampere flowing for one minute. It's commonly used in battery specifications and some electrical engineering calculations.

What is a Coulomb?

A coulomb (C) is the standard SI unit of electrical charge. It is defined as the amount of charge transferred by a current of one ampere in one second. Named after the French physicist Charles-Augustin de Coulomb, this unit is fundamental in electrical engineering and physics.

The Conversion Formula

To convert ampere-minutes to coulombs, use the following formula:

1 Ampere-Minute = 60 Coulombs

This is because: 1 Ampere × 1 Minute = 1 Ampere × 60 Seconds = 60 Coulombs

Conversion Table: Ampere-Minutes to Coulombs

Here's a handy conversion table to help you quickly estimate conversions:

Ampere-Minutes	Coulombs
1 A·min	60 C
2 A·min	120 C
5 A·min	300 C
10 A·min	600 C
20 A·min	1200 C
50 A·min	3000 C
100 A·min	6000 C

Practical Examples and Calculations

Let's explore some real-world examples to illustrate the use of the Ampere-Minute to Coulomb Converter:

Example 1: Battery Capacity

Suppose you have a battery rated at 2000 mAh (milliampere-hours). How many coulombs of charge does it hold?

Step 1: Convert mAh to Ah 2000 mAh = 2 Ah

Step 2: Convert Ah to A·min 2 Ah = 2 A·min × 60 = 120 A·min

Step 3: Convert A·min to Coulombs 120 A·min × 60 C/A·min = 7200 C

Therefore, the battery holds 7200 coulombs of charge.

Example 2: Electric Vehicle Charging

An electric vehicle charger supplies 30 amperes for 20 minutes. How many coulombs of charge are transferred?

Step 1: Calculate Ampere-Minutes 30 A × 20 min = 600 A·min

Step 2: Convert A·min to Coulombs 600 A·min × 60 C/A·min = 36,000 C

The charging session transferred 36,000 coulombs of charge to the vehicle's battery.
