What is Electric Charge?

Electric charge is a basic property of matter. It makes electricity work in our daily lives. Think of it as the amount of electrical energy stored in something. When you charge your phone, you are putting electric charge into the battery.

Electric charge is measured in different units. The most common unit is the coulomb (C). Other popular units include ampere-hours (Ah) and milliampere-hours (mAh). These units help us understand how much electrical energy something can hold or use.

Our electric charge converter helps you change between these different units easily. This is useful when working with batteries, electronics, or electrical systems.

Common Electric Charge Units

Coulomb (C)

The basic unit of electric charge. Named after Charles-Augustin de Coulomb. One coulomb equals the charge of about 6.24 × 10¹⁸ electrons.

Ampere-hour (Ah)

Shows how much charge flows in one hour at one ampere. Commonly used for car batteries and large electrical systems.

Milliampere-hour (mAh)

One thousandth of an ampere-hour. Used for small devices like phones, tablets, and portable electronics.

Faraday (F)

Named after Michael Faraday. Used in chemistry and electrochemistry. One faraday equals about 96,485 coulombs.

Real-World Electric Charge Examples

Smartphone Battery

A typical smartphone battery holds about 3000 mAh of charge. This equals 10,800 coulombs of electric charge.

3000 mAh = 10,800 C

Car Battery

A standard car battery has about 50 Ah capacity. This is the same as 180,000 coulombs of charge.

50 Ah = 180,000 C

Laptop Battery

Most laptop batteries store around 4000-6000 mAh. A 5000 mAh battery equals 18,000 coulombs.

5000 mAh = 18,000 C

Power Bank

A portable power bank might have 10,000 mAh capacity. This stores 36,000 coulombs of electric charge.

10,000 mAh = 36,000 C

Electric Vehicle

An electric car battery can hold 60-100 kWh. A 75 kWh battery equals about 270 million coulombs.

75 kWh ≈ 270,000,000 C

Watch Battery

A small watch battery holds about 200 mAh. This equals 720 coulombs of charge.

200 mAh = 720 C

Electric Charge Conversion Formulas

Coulomb to Ampere-hour

Ah = C × 0.000277778

Divide coulombs by 3600 to get ampere-hours

Ampere-hour to Coulomb

C = Ah × 3600

Multiply ampere-hours by 3600 to get coulombs

mAh to Coulomb

C = mAh × 3.6

Multiply milliampere-hours by 3.6 to get coulombs

Coulomb to mAh

mAh = C × 0.277778

Divide coulombs by 3.6 to get milliampere-hours

Tips for Working with Electric Charge

Battery Life Calculation

To find how long a battery lasts, divide the battery capacity (mAh) by the device's current draw (mA). For example, a 3000 mAh battery powering a 300 mA device will last about 10 hours.

Charging Time Estimation

Charging time depends on the charger's current output. A 2A charger will fill a 4000 mAh battery in about 2 hours (4000 mAh á 2000 mA = 2 hours).

Power Bank Selection

Choose a power bank with at least 1.5 times your device's battery capacity. This accounts for energy loss during charging and gives you extra power.

Unit Conversion Memory Trick

Remember: 1 Ah = 1000 mAh = 3600 C. Think of it as 1 hour = 60 minutes = 3600 seconds, but with different units for electric charge.

Frequently Asked Questions

What is the difference between mAh and Ah?

mAh stands for milliampere-hour, while Ah stands for ampere-hour. 1 Ah equals 1000 mAh. Small devices use mAh, while larger systems use Ah.

How do I convert coulombs to mAh?

To convert coulombs to mAh, multiply the coulomb value by 0.277778. For example, 3600 C × 0.277778 = 1000 mAh.

Why are there different units for electric charge?

Different units suit different applications. Coulombs are used in physics, mAh for small electronics, Ah for car batteries, and Faradays in chemistry.

Is this converter accurate for all calculations?

Yes, our converter uses precise conversion factors. It's accurate for engineering, scientific, and everyday calculations involving electric charge units.

Can I use this for battery capacity comparisons?

Absolutely! Convert all battery capacities to the same unit (like mAh) to easily compare which battery holds more charge.
