How to convert terawatts to megawatts?

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

1 terawatt = 1,000,000 megawatts
TW to MW formula: MW = TW × 1,000,000

Quick examples

0.5 TW = 0.5 × 1,000,000 = 500,000 MW
2 TW = 2 × 1,000,000 = 2,000,000 MW
0.0003 TW = 0.0003 × 1,000,000 = 300 MW

Tip: Moving from tera- to mega- is a jump of six powers of ten, so you multiply by 1,000,000.

Frequently asked questions

What is the terawatts to megawatts conversion?

Terawatts to megawatts is a unit conversion for power. It changes a value in terawatts (TW) into the same power amount in megawatts (MW). Both units measure the rate of energy use or output.

How many megawatts are in 1 terawatt?

1 terawatt equals 1,000,000 megawatts.
1 TW = 1,000,000 MW

What is the formula to convert terawatts to megawatts?

Multiply terawatts by 1,000,000.
MW = TW × 1,000,000

How do you convert megawatts to terawatts?

Divide megawatts by 1,000,000.
TW = MW ÷ 1,000,000

Why is 1 terawatt equal to 1,000,000 megawatts?

The metric prefixes explain it.

Tera- means 10¹²
Mega- means 10⁶

So, 10¹² ÷ 10⁶ = 10⁶, which is 1,000,000.

What are common examples of terawatts and megawatts?

Terawatts often describe very large totals, like a country’s power demand or global power use at a moment in time. Megawatts often describe power plants, wind farms, and large factory loads.

What is 0.5 terawatts in megawatts?

Use the formula MW = TW × 1,000,000.
0.5 × 1,000,000 = 500,000
0.5 TW = 500,000 MW

What is 0.001 terawatts in megawatts?

0.001 × 1,000,000 = 1,000
0.001 TW = 1,000 MW

Can terawatts and megawatts measure electricity generation and usage?

Yes. Both units measure power, which fits electricity generation (output) and electricity demand (use). The unit stays the same whether you talk about a plant producing power or a grid using power.

Is terawatt (TW) a unit of energy or power?

Terawatt (TW) is a unit of power, not energy. Power is a rate. Energy depends on time.

How do you convert terawatts to megawatt-hours?

You can’t convert TW to MWh without time. First convert TW to MW, then multiply by hours.

MW = TW × 1,000,000
MWh = MW × hours

Example: 2 TW for 3 hours
2 TW = 2,000,000 MW
Energy = 2,000,000 MW × 3 h = 6,000,000 MWh

What’s the difference between MW and MWh?

MW measures power at a moment. MWh measures energy over time.

1 MW is a rate.
1 MWh is 1 MW used for 1 hour.

Do I need to worry about rounding when converting TW to MW?

It depends on your use. For quick estimates, rounding is fine. For reporting or billing, keep enough decimal places in terawatts to avoid big changes after multiplying by 1,000,000.

What are the symbols for terawatt and megawatt?

Terawatt: TW
Megawatt: MW

Use uppercase letters. Case matters in unit symbols.
