Ampere-hours to Milliampere-hours Converter

Enter charge in ampere-hours:

Additional Conversion:

1 Ampere-hour (Ah) = 1000 Milliampere-hours (mAh)

1 Milliampere-hour (mAh) = 0.001 Ampere-hours (Ah)

Conversion Formula:

Q(mAh) = Q(Ah) × 1000

Example:

Convert 3 ampere-hours to milliampere-hours:

Q(mAh) = 3Ah × 1000 = 3000mAh

Conversion Result:

3 ampere-hours is equal to 3000 milliampere-hours.

Overview

An Ampere-hours to Milliampere-hours Converter is a tool that converts battery capacity between ampere-hours (Ah) and milliampere-hours (mAh). This conversion is essential for comparing battery capacities in consumer electronics (smartphones, laptops), electric vehicles (EVs), and power banks, where mAh is commonly used for smaller batteries and Ah for larger ones.

Key Concepts

1. Ampere-hour (Ah)

• A unit of electric charge capacity representing 1 amp of current flowing for 1 hour.

• Used for large batteries (e.g., car batteries, solar storage).

2. Milliampere-hour (mAh)

• A subunit of Ah, where 1 Ah = 1000 mAh.

• Used for smaller batteries (e.g., phones, power banks).

Conversion Formula

1. Ah to mAh

$$\text{mAh}=\text{Ah}\times 1000$$

Example:

• 2.5 Ah → mAh:

  $$2.5\times 1000=2500\text{ mAh}$$

2. mAh to Ah

$$\text{Ah}=\frac{\text{mAh}}{1000}$$

Example:

• 5000 mAh → Ah:

  $$\frac{5000}{1000}=5\text{ Ah}$$
