Millivolt (mV)
Definition: A millivolt (symbol: mV) is a submultiple of the volt, equal to one-thousandth (1/1,000) of a volt.
History/origin: As scientific instruments became more sensitive in the late 19th century, the millivolt became essential for measuring small electrochemical reactions and biological signals.
Current use: Millivolts are used extensively in medical diagnostics (ECG/EEG), measuring sensor outputs (like thermocouples), and in high-precision electronics testing.
Volt (V)
Definition: The volt (symbol: V) is the SI derived unit of electric potential, electric potential difference (voltage), and electromotive force. It is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.
History/origin: The unit is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery.
Current use: The volt is the universal standard for measuring electrical potential in household electronics, batteries, and power distribution systems worldwide.
Millivolt (mV) to Volt (V) Conversion Table
| Millivolt (mV) [mv] | Volt (V) [v] |
|---|---|
| 0.01 mv | 0.00001 v |
| 0.1 mv | 0.0001 v |
| 1 mv | 0.001 v |
| 2 mv | 0.002 v |
| 3 mv | 0.003 v |
| 5 mv | 0.005 v |
| 10 mv | 0.01 v |
| 20 mv | 0.02 v |

How to Convert Millivolt (mV) to Volt (V)
1 mv = 0.001 v
1 v = 1000 mv
Example: convert 15 mv to v:
15 mv = 15 × 0.001 v = 0.015 v
Did You Know?
- Millivolts (mV) are used to measure tiny electrical signals in the human body. For example, an ECG machine detects signals from your heart that are often only a few millivolts in strength.
- Did you know? Different countries use different voltages! While most of the world (including Bangladesh and Europe) uses 220-240V, North America uses 110-120V for standard household outlets.
