What is the difference between W (Watts) and VA (Volt-Amps)?

For many items the two are identical however for some computer equipment the two can differ, VA ratings always being equal or higher than the W rating. The ratio of W to VA is known as the Power Factor (often represented as a decimal or percentage). 

How do I know how many Watts my items use?

Most manufacturers of electrical devices and appliances show the amount of Watts or Amps used somewhere on their product, product box, published specifications or their website.
