## What Are Watts and Gigawatts?

Before diving into the conversion of **3.49e10 watts to gigawatts**, it’s essential to understand the basic concepts behind these units of power measurement.

### Watts: The Building Block of Power Measurement

**Watts (W)** are the standard unit of power in the International System of Units (SI). Named after James Watt, a pioneer in steam engine technology, watts measure the rate at which energy is generated or consumed. One watt is equivalent to one joule of energy per second. In more practical terms, a watt is the power required to do one unit of work in one second.

Watts are commonly used in everyday contexts to quantify the power consumption of household appliances. For example:

- A typical light bulb may consume between
**10 and 100 watts**. - A microwave oven might consume
**1,000 watts**or**1 kilowatt (kW)**.

### Gigawatts: Measuring Massive Power Outputs

When dealing with immense amounts of power, the **gigawatt (GW)** is a more practical unit. A gigawatt is equal to **one billion watts** or **1,000 megawatts (MW)**. Gigawatts are commonly used to express the power generation capacity of entire power plants, national grids, or large renewable energy projects.

To put it in perspective:

- A large coal-fired power plant typically has a capacity of around
**1 GW**. - Some of the largest hydroelectric plants in the world can produce up to
**22 GW**(e.g., the Three Gorges Dam in China).

## Converting 3.49e10 Watts to Gigawatts

### Understanding the Scientific Notation “3.49e10”

The notation **3.49e10** represents a number in scientific notation, where **“e”** denotes “times ten raised to the power of.” Therefore, **3.49e10** can be read as **3.49 × 10^10** or **34,900,000,000 watts**.

### Conversion Formula: Watts to Gigawatts

To convert watts to gigawatts, we need to divide the number of watts by **1 billion (10^9)**, since there are **1 billion watts in one gigawatt**. Mathematically, the conversion can be expressed as:Gigawatts (GW)=Watts (W)109\text{Gigawatts (GW)} = \frac{\text{Watts (W)}}{10^9}Gigawatts (GW)=109Watts (W)

Now let’s apply this formula to our given value.

### Step-by-Step Conversion of 3.49e10 Watts to Gigawatts

**Step 1**: Write down the value to be converted:**3.49e10 W**.**Step 2**: Divide the value by**10^9**to convert to gigawatts.

Gigawatts (GW)=3.49×1010109\text{Gigawatts (GW)} = \frac{3.49 \times 10^{10}}{10^9}Gigawatts (GW)=1093.49×1010

**Step 3**: Simplify the expression:

Gigawatts (GW)=3.49×1010−9=3.49×101=34.9 GW\text{Gigawatts (GW)} = 3.49 \times 10^{10 – 9} = 3.49 \times 10^1 = 34.9 \text{ GW}Gigawatts (GW)=3.49×1010−9=3.49×101=34.9 GW

Thus, **3.49e10 watts is equal to 34.9 gigawatts**.
