How to Convert Volts and Amps to Watts and Other Formulas

Unit conversions sometimes can be difficult, but with most basic electric units like the voltage, current, and power, things are almost always very simple. CCTV Camera Pros is a direct supplier of video surveillance equipment for home, business, and government.Here is simple volts and amps to watts calculator, with short explanations, formulas, and charts. This online calculator was created by Mike Haldas for CCTV Camera Pros. Please visit our Calculators, Converters, and Tools page for additional online applications.

Ohm’s Law – Ohm’s Law states that when electric current flows through a conductor (such as a cable), the intensity of the current (amps) equals the electromotive force (volts) driving it, divided by the resistance of the conductor.

One ohm is the amount of resistance that limits current flow to one amp in a circuit with one volt of electrical pressure. This is similar to how a tube or hose applies resistance to the flow of water. Electrical conductors (such as a wire) apply resistance to the flow of current.

Ohm – unit for measuring the resistance of flow in an electrical current.

Amps are used to measure electricity flow similarly to how GPM (gallons per minute) are used to measure the volume of water flowing. One amp is the amount of current when one volt of electrical pressure is applied against one ohm of resistance.

Amp (Ampere) – unit of measure of the flow rate of current in an electrical circuit.

Watts are calculated by multiplying the current (measured in amps) by the electrical pressure (measured in volts). Watts are also known as volt-amps and are a unit of electrical measurement typically used in AC power circuits.

Watt – unit of measure of the electrical power applied in a circuit.

The concept is similar to water pressure. One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance.

Volt – unit of measure of the electrical force or pressure which causes an electricity current to flow in a circuit.

Here are some useful electrical terms related to calculating volts to watts, watts to amps, and volts to amps. In the above calculator, the installer will enter a value of 24 in the volts field and a value of 50 in the watts field. For example a 24VAC50 power supply is 24 volt, 50 volt-amps (watts are also known as volt-amps). Typically, 24V AC power supplies have VA (voltage amps) ratings and not amps.

They first need to calculate how many amps a 24V AC power supply outputs. The installer needs to calculate the distance that a power cable can be run from a security camera DVR to a CCTV camera, HD security camera, and even one of the latest UHD 4K security cameras.

Here is one example of how this calculator is commonly used by security system installers as an amp calculator. The formula to convert amps to watts at a fixed voltage is: watts = amps x volts. The formula to convert volts to amps at a fixed wattage is: amps = watts / volts.

The formula to convert watts to amps at a fixed voltage is amps = watts / volts. The formula to convert voltage to watts is watts = amps x volts. Click Calculate.Įxample 2: To convert watts to amps for a 12V DC 500mA power supply, enter 12 volts and. Convert / CalculateĮxample 1: To convert volts to amps for a 24V VA50 power supply, enter 24 volts and 50 Watts. This tool can convert any value as long as you enter the two other values. The calculator works by filling in any of two of the three fields (volts amps watts) to calculate the value of the third field. Our online calculator / conversion tool can convert watts to amps, volts to watts, and volts to amps.
