The milliampere-hour (mAh) is a unit of electric charge that is commonly used to measure the capacity of batteries. It indicates how much current a battery can deliver over a specific period. For instance, a battery rated at 1000 mAh can theoretically provide 1000 milliamperes (mA) of current for one hour before it is fully discharged.
The milliampere-hour is part of the International System of Units (SI) and is derived from the ampere, which is the base unit of electric current. The symbol for milliampere-hour is mAh, where "milli" denotes a factor of one-thousandth. This standardization allows for consistent measurements across various applications, making it easier for users to understand battery capacities and performance.
The concept of measuring electric charge dates back to the early days of electricity. The milliampere-hour emerged as a practical unit in the 20th century, particularly with the rise of portable electronic devices. As technology advanced, the demand for efficient battery capacities increased, leading to the widespread adoption of mAh as a standard measurement in consumer electronics.
To illustrate how to use the milliampere-hour measurement, consider a smartphone battery rated at 3000 mAh. If the phone consumes 300 mA of current during usage, you can calculate the approximate usage time as follows:
[ \text{Usage Time (hours)} = \frac{\text{Battery Capacity (mAh)}}{\text{Current Consumption (mA)}} ] [ \text{Usage Time} = \frac{3000 \text{ mAh}}{300 \text{ mA}} = 10 \text{ hours} ]
The milliampere-hour is crucial for consumers when selecting batteries for devices such as smartphones, tablets, and laptops. Understanding mAh helps users gauge how long their devices can operate on a single charge, enabling informed decisions when purchasing or replacing batteries.

The milliohm (mΩ) is a unit of electrical resistance in the International System of Units (SI). It is equal to one-thousandth of an ohm (Ω), which is the standard unit for measuring electrical resistance. Understanding milliohms is crucial for professionals in electrical engineering, electronics, and related fields, as it allows for precise measurements in low-resistance applications.
The milliohm is standardized under the SI unit system, ensuring consistency and reliability in electrical measurements. It is commonly used in various applications, including electrical circuits, power systems, and electronic devices, where low resistance values are prevalent.
The concept of resistance was first introduced by Georg Simon Ohm in the 1820s, leading to the formulation of Ohm's Law. As technology advanced, the need for more precise measurements in low-resistance scenarios emerged, giving rise to the milliohm as a practical unit. Over the years, the milliohm has become essential in fields such as telecommunications, automotive engineering, and renewable energy systems.
To illustrate the use of milliohms, consider a scenario where a circuit has a total resistance of 0.005 Ω. To convert this to milliohms, simply multiply by 1,000: [ 0.005 , \text{Ω} \times 1000 = 5 , \text{mΩ} ] This conversion is vital for engineers who need to work with low resistance values accurately.
Milliohms are particularly useful in applications such as:
