Welcome to **volts to watts**, our website explaining the conversion of the voltage (V) in volts to the electrical power (P) in watts.

If you have been wondering *how many watts in a volt*, or if you have been searching for volt to watt, then you have definitively come to the right site.

Here you can find the power consumption in watts for a given voltage supply, assumed the amperage (I) in ampere is known; the relation between volt and watt is P = I × V.

The unit symbols are W for watts, A for ampere and V for volts. Read on to learn how to convert volts to watts, and make sure to try out our converter further down on this page.

## Convert Volts to Watts

There is no direct relation between voltage and electrical power consumption. For this conversion the amperage must be known, too. To convert volts to watts use the formulas:

- Direct Current (DC):
**P**_{(W)}= I_{(A)}× V_{(V)} - Alternating Current (AC), 1 Phase:
**P**_{(W)}= PF × I_{(A)}× V_{(V)} - Alternating Current (AC), 3 Phase, Line to Line (L-L):
**P**_{(W)}= √3 × PF × I_{(A)}× V_{(V)} - Alternating Current (AC), 3 Phase, Line to Neutral (L-N):
**P**_{(W)}= 3 × PF × I_{(A)}× V_{(V)}

For example, supposed your current is 1.5A and your voltage supply is 60V:

- In case of direct current, in order to convert multiply the electric current in ampere by the voltage in watts. As a result, the power consumption in watts is 90W (1.5A × 60V).
- In case of 1 phase AC, multiply the electric current by the voltage, then multiply the term by the power factor PF. Assumed a PF of 0.6, the power consumption is 54W (1.5A × 60V × 0.6).
- For 3 phase AC L-L, multiply the current by the voltage, then multiply the term by the power factor PF and √3. For a PF of 0.6, the power consumption is 93.53W (√3 × 1.5A × 60V × 0.6).
- For 3 phase AC L-N, multiply the current by the voltage, then multiply the term by the power factor PF and 3. Supposed a PF of 0.6, the power consumption is 162W (3 × 1.5A × 60V × 0.6).

### Terms

__Power factor__: In an AC circuit, the power factor PF is defined as the ratio real power / apparent power.

__Real power__: The real power is the net transfer of energy passing in one direction, whereas the apparent power is the vector sum of real power + reactive power.

Further Information:

not sure what PF means in this equation ?? Also not sure what the Phases are ?

Hi. I’m wondering if this formula also applies with power banks (mobile) and lithium batteries.

Example: I have a device that requires 15v/1A power, if i want to power this device when no power is available for say 2 hrs what are the key specs to look for in a power bank? What is the correct conversion equation I can use to figure these things out on my own? There are sooo many options and they market the products in Watts and mAhs, some with power outlets some without.

Your help is greatly appreciated.
