How to convert electron volts to watt seconds (eV to Ws)

The formula for converting electron volts to watt seconds is: Ws = eV × 1.602176487e-19. To calculate the electron volt value in watt seconds first substitute the electron volt value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 electron volt in watt seconds we follow these steps:

Ws = eV × 1.602176487e-19

Ws = 1 × 1.602176487e-19

Ws = 0.0000000000000000001602176487

In other words, 1 electron volt is equal to 0.0000000000000000001602176487 watt seconds.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 7 electron volts to watt seconds is:

  1. Understand the conversion formula: Ws = eV × 1.602176487e-19
  2. Substitute the required value. In this case we substitute 7 for eV so the formula becomes: Ws = 7 × 1.602176487e-19
  3. Calculate the result using the provided values. In our example the result is: 7 × 1.602176487e-19 = 1.1215235409e-18 Ws

In summary, 7 electron volts is equal to 1.1215235409e-18 watt seconds.

Converting watt seconds to electron volts

In order to convert the other way around i.e. watt seconds to electron volts, you would use the following formula: eV = Ws × 6241509647120400000. To convert watt seconds to electron volts first substitute the watt second value into the above formula, and then execute the calculation. If we wanted to calculate 1 watt second in electron volts we follow these steps:

eV = Ws × 6241509647120400000

eV = 1 × 6241509647120400000

eV = 6241509647120400000

Or in other words, 1 watt second is equal to 6241509647120400000 electron volts.

Conversion Unit Definitions

What is a Electron Volt?

An electron volt (eV) is a unit of energy used in physics and atomic sciences. It is the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
Mathematically, one electron volt is equal to 1.60218 × 10−19 joules. The electron volt is a very small unit of energy, but it is convenient for describing atomic and subatomic processes because the energies involved at the atomic and molecular scale are typically quite small.
In particle physics and quantum mechanics, energies of particles and radiation are often expressed in electron volts. For example, the rest mass energy of an electron is approximately 511,000 eV, and the energy of visible light photons is typically in the range of 1.65 − 3.1 eV.

What is a Watt Second?

A watt-second (Ws), also known as a joule (J), is a unit of energy in the International System of Units (SI). It represents one watt of power expended for one second. Mathematically, it can be defined as: 1 watt-second (Ws) = 1 watt (W) × 1second (s) = 1 joule (J).
Watt-seconds are used to measure the energy consumed or produced by electronic devices or electrical systems in a very short amount of time. For example, the energy released by a camera flash, the energy stored in capacitors, or the energy consumed by a small electronic circuit during its operation can be measured in watt-seconds.
In practical terms, a watt-second is a relatively small unit of energy. To provide some context, 1 watt-second is equivalent to the energy required to power a 1-watt device for 1 second.
