Convert Terawatts to Petawatts

To convert terawatts (TW) to petawatts (PW), use the SI prefix sizes: tera = 10¹² and peta = 10¹⁵. That means 1 petawatt equals 1,000 terawatts.

• Conversion factor: 1 TW = 0.001 PW
• Formula: PW = TW × 0.001
• Reverse check (optional): TW = PW × 1,000

Example:

• 500 TW × 0.001 = 0.5 PW

This terawatts to petawatts conversion works the same for any power value in watts.

What’s the difference between a terawatt and a petawatt?

A terawatt (TW) is 1,000,000,000,000 watts (10^12 W). A petawatt (PW) is 1,000,000,000,000,000 watts (10^15 W). A petawatt is 1,000 times larger than a terawatt.

How do you convert terawatts to petawatts?

Divide terawatts by 1,000 to get petawatts.
Formula: PW = TW ÷ 1,000

How do you convert petawatts to terawatts?

Multiply petawatts by 1,000 to get terawatts.
Formula: TW = PW × 1,000

How many terawatts are in 1 petawatt?

There are 1,000 terawatts in 1 petawatt.
1 PW = 1,000 TW

How many petawatts are in 1 terawatt?

There are 0.001 petawatts in 1 terawatt.
1 TW = 0.001 PW

What do TW and PW mean in power units?

TW stands for terawatt and PW stands for petawatt. Both measure power, which is the rate of energy use or energy transfer over time.
1 watt = 1 joule per second

Are terawatts and petawatts used for energy or power?

They are used for power, not energy. Power is a rate. Energy is power over time. For example, terawatt-hours (TWh) measure energy, while terawatts (TW) measure power.

What’s the formula to convert TW to PW and PW to TW?

Use these simple conversion rules:

• TW to PW: PW = TW ÷ 1,000
• PW to TW: TW = PW × 1,000

What are common examples of terawatt-scale power?

Terawatts often describe very large power levels, like national or global electricity use, large grids, and peak demand across wide regions. They’re also used in big energy planning and long-term projections.

Where are petawatts used in real life?

Petawatts show up in extreme cases, most often in high-power laser pulses in labs. These pulses can reach petawatt-level peak power for a very short time, even though the total energy may be limited.

Does petawatt power mean a device uses that much energy?

Not always. A petawatt rating can describe peak power for a brief moment. Energy depends on how long the power lasts. A short pulse can have huge power but modest total energy.

How do you write terawatts and petawatts in scientific notation?

• 1 TW = 10^12 W
• 1 PW = 10^15 W
  This makes it easy to compare sizes and convert between units.

What’s a quick mental math trick for TW to PW conversion?

Move the decimal three places:

• TW to PW: move left 3 places (divide by 1,000)
• PW to TW: move right 3 places (multiply by 1,000)
  Example: 2.5 TW = 0.0025 PW, and 0.4 PW = 400 TW.

Can you convert TW to PW without losing accuracy?

Yes, as long as you keep enough decimal places. Since the conversion is a clean factor of 1,000, the math is exact. Rounding is the only source of error.

What unit is larger than a petawatt?

The next step up is the exawatt (EW).
1 EW = 1,000 PW = 10^18 W
