Prior to discussing how to convert watts to joules per second, lets define a watt and a joule. Watt is a unit of power and it measures the amount of energy an item needs to function while a joule is the SI unit of work or energy and is equal to the work done by a force of one newton acting through one meter.

Joule per second is the unit of action or of angular momentum.

A watt is equivalent to one joule per second.

### Formula to Convert Watts to Joules per Second.

Since we know that 1W is equal to 1J.s. Therefore, to convert W to J.s, we multiply the W value by 1.

**Example 1:**

Convert the energy of a 60W bulb to J/sec.

**= 60 x 1**

**= 60 J.s**

**Example 2:**

Convert 0.01 watts to J/sec.

**1W = 1J/sec**

**= 0.01 x 1**

**= 0.01 joules per second**

**Example 3:**

Convert 1000 watts to J/s.

**1W = 1J/sec**

**= 1000 x 1**

**= 1000 J/s**
