Converting 3.49e10 Watts to GW
Now, let’s tackle the main question: how do we convert 3.49e10 watts to gigawatts (GW)?
- First, recall that 1 gigawatt (GW) = 1,000,000,000 watts (1 billion watts)
- To convert watts to gigawatts, we divide by 1,000,000,000
- So, 3.49e10 watts รท 1,000,000,000 = 34.9 GW
Therefore, 3.49e10 watts equals 34.9 gigawatts (GW).
