While watts is the SI unit of power equivalent to 1 joule per second, a gigawatt is also a unit of power that is equivalent to one billion watts.

While the abbreviation for watts is W, the abbreviation for gigawatts is GW.

**Formula to convert GW to W.**

To convert GW to W, need to know their relationship first.

We can see that from the definition of GW, one GW is equivalent to one billion watts.

Therefore, to convert GW to W, we multiply the GW value by 1,000,000,000.

**GW = W x 1,000,000,000**

**Example:**

Convert 50 gigawatts to watts.

**= 50 x 1,000,000,000**

**= 50,000,000,000 watts.**
