Convert Megawatts to Terawatts

To convert megawatts (MW) to terawatts (TW), use the metric prefixes:

• Mega means 10⁶ (one million)
• Tera means 10¹² (one trillion)

That means 1 TW = 1,000,000 MW, so converting MW to TW means you divide by 1,000,000.

Formula (MW to TW):

• TW = MW ÷ 1,000,000
• TW = MW × 10⁻⁶

Quick examples:

• 500,000 MW = 0.5 TW
• 1,000,000 MW = 1 TW
• 25 MW = 0.000025 TW

Tip: If you want to convert terawatts to megawatts, go the other way and multiply by 1,000,000.

How many terawatts are in a megawatt?

There are 0.000001 terawatts (TW) in 1 megawatt (MW).
That’s because 1 TW = 1,000,000 MW.

What is the formula to convert megawatts to terawatts?

Use this conversion formula:
TW = MW ÷ 1,000,000
You can also write it as: TW = MW × 10⁻⁶.

How do you convert terawatts to megawatts?

To go the other way, multiply by one million:
MW = TW × 1,000,000

What is 1 MW in TW?

1 MW = 0.000001 TW.
It’s one-millionth of a terawatt.

What is 10 MW in TW?

10 MW = 0.00001 TW.
Divide 10 by 1,000,000 to get the result.

What is 100 MW in TW?

100 MW = 0.0001 TW.
This is one ten-thousandth of a terawatt.

What is 1,000 MW in TW?

1,000 MW = 0.001 TW.
A thousand megawatts equals one-thousandth of a terawatt.

What is 1,000,000 MW in TW?

1,000,000 MW = 1 TW.
This is the key reference point for the scale.

Why is the MW to TW conversion factor 1,000,000?

Both units measure power in watts.

• 1 MW = 10⁶ watts
• 1 TW = 10¹² watts
  The difference is 10¹² ÷ 10⁶ = 10⁶, which is 1,000,000.

What’s the difference between megawatts and terawatts?

A megawatt measures large power output, like a wind turbine or small plant.
A terawatt measures massive power, like a whole region’s demand or global totals.
1 TW equals 1,000,000 MW, so the terawatt is much larger.

Are megawatts and terawatts units of power or energy?

They are units of power, not energy. Power is the rate of using or making energy.
Energy uses time-based units, like:

• MWh (megawatt-hours)
• TWh (terawatt-hours)

How do MW and TW relate to watts?

They are both watt-based units:

• 1 MW = 1,000,000 W
• 1 TW = 1,000,000,000,000 W
  This helps when you need to convert across many unit sizes.

What’s a quick way to estimate MW to TW in your head?

Move the decimal point 6 places left when converting MW to TW.
Example: 500,000 MW = 0.5 TW.
Move the decimal point 6 places right to convert TW back to MW.

When would you use terawatts instead of megawatts?

Use megawatts (MW) for single sites and equipment output.
Use terawatts (TW) for very large totals, like national grids or global power use.
The larger the system, the more sense TW makes.

Can MW to TW conversions be exact?

Yes. The conversion is based on powers of ten, so it’s exact.
Any rounding comes from how many decimal places you choose to show.
