MW h(megawatt hour)
A megawatt hour (MWh) is a unit of energy used in the field of energy, particularly in the electric power sector. It is a measure of the amount of electrical energy produced, consumed, or stored by a device or system. One megawatt hour is equivalent to the continuous consumption or production of one million watts (1 megawatt, or 1,000 kilowatts) of electricity for one hour.
To put it simply, if a power plant generates 1 megawatt of electricity continuously for one hour, it produces 1 megawatt hour of energy. MWh is commonly used to express the output of power plants, the energy usage of large facilities, and the total consumption or generation of electricity in a geographical area over a specific time period.
mW h(milliwatt hour)
A milliwatt-hour (mWh) is a unit of energy used to measure small amounts of electrical energy. It is a derived unit from the standard unit of energy, called the watt-hour (Wh). A milliwatt-hour represents one-thousandth of a watt-hour, or the amount of energy used by a device with a power consumption of one milliwatt operating for one hour.
In the field of energy, the mWh unit is commonly used to measure and quantify the energy consumption or production of small-scale devices, such as wearable electronics, sensors, and other low-power devices. It helps in understanding their power requirements, battery life, and energy efficiency.
To put it into perspective, a device that draws a power of 1 milliwatt (1/1000 watt) and continuously operates for 1 hour will consume 1 milliwatt-hour (mWh) of energy. Similarly, if a device consumes 2 milliwatts of power and runs for 3 hours, it will use 6 milliwatt-hours (6 mWh) of energy.
The megaelectron volt (MeV) is a unit of energy in the field of physics, particularly in particle and nuclear physics. It represents one million electron volts (eV). An electron volt is the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt.
In the context of energy, 1 eV is equal to 1.602 x 10^-19 joules. Therefore, 1 MeV is equal to 1.602 x 10^-13 joules. Because the electron volts (and by extension, megaelectron volts) are relatively small units of energy, they are used to describe the energies of particles, like electrons, protons, and photons, at the atomic and subatomic scale.
In nuclear and high-energy particle physics, MeV is frequently used to express the masses of subatomic particles through the concept of mass-energy equivalence, given by Einstein's famous equation E=mc^2. This means that an MeV can also be considered a unit of mass for subatomic particles.
The millielectron volt (meV) is a unit of energy commonly used in the field of physics, particularly in atomic, molecular, nuclear, and particle physics. It is a submultiple of the electron volt (eV), where 1 electron volt is defined as the amount of kinetic energy gained by a single electron when it is accelerated through an electric potential difference of one volt.
1 millielectron volt (meV) is equal to one-thousandth (1/1000) of an electron volt, or 0.001 eV. Its value in the International System of Units (SI) is about 1.602 x 10^(-22) joules.
This unit is used to describe energy levels, energy differences or energy transfers on a small scale, such as in atomic and molecular interactions, quantum states transitions, and properties of subatomic particles. Because these interactions involve very small amounts of energy, the use of meV makes it more practical and convenient to express and compare these values without resorting to scientific notation or very small decimal numbers.
