## How do you calculate watts?

**AC three phase amps to watts calculation formula**

- P
_{(}_{W}_{)}= √3 × PF × I_{(}_{A}_{)}× V_{L-L}_{(}_{V}_{)}So watts are equal to square root of 3 times power factor PF times amps times volts: - watt = √3 × PF × amp × volt. or.
- W = √3 × PF × A × V. Example. …
- P = √3 × 0.8 × 3A × 110V = 457W. Watts calculation with line to neutral voltage.

## Can I put a 100W LED bulb in a 60w?

However, LED’s do not emit dangerous levels of heat. Thus, if your fixture says “**not to exceed** 60-Watts” but you want to use a 100-Watt equivalent LED bulb, this would be safe to do so. … For a 60-Watt fixture, you could use a 100W, 125W, or even 150W LED equivalent because they all consume under 60-Watts!

## WHAT LED bulb equals 60 watts?

A 60-watt incandescent light bulb can be replaced with a **10-watt LED**.

## Is 40w brighter than 60w?

40-watt bulb produces **450 lumens** of light. 60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light.

## How do I know what wattage my outlet is?

If you want to know how many watts you can safely draw from an outlet, **multiply the voltage and amperage ratings for that circuit**. In the U.S., most circuits are rated for 120 volts and either 15 or 20 amps. Therefore, the safe max wattage for most standard outlets is either 1800 W or 2400 W.

## How do I know what wattage my adapter is?

Wattage is the overall measurement of power that flows through your charger, so a higher cell phone charger wattage means that your device will charge faster. If you’re shopping for a new charger and the wattage isn’t listed, you can also calculate it with the formula: **watts = volts x amps.**
