In 1 kilowatts there are 1.00000e-9 terawatts. Meanwhile in 1 terawatts there are 1,000,000,000 kilowatts. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Terawatts to Kilowatts calculator above to convert any number.

To convert kilowatts (kW) to terawatts (TW), divide by 1,000,000,000 (10^9). A kilowatt is a smaller unit of power, often used for devices and home energy use, while a terawatt is used for very large power levels.
Example:
To convert kilowatts to terawatts, divide the kilowatt value by 1,000,000,000.
1 terawatt equals 1,000,000,000 kilowatts, so the number gets much smaller in TW.
Use this formula:
TW = kW ÷ 1,000,000,000
This works because kW and TW are both units of power, just at very different scales.
1 kW = 0.000000001 TW (1 × 10⁻⁹ TW)
A kilowatt is one-billionth of a terawatt.
1 TW = 1,000,000,000 kW (1 × 10⁹ kW)
Terawatts are used for very large power levels, like national or global totals.
100,000 kW = 0.0001 TW
Calculation: 100,000 ÷ 1,000,000,000 = 0.0001.
1,000,000 kW = 0.001 TW
That’s one-thousandth of a terawatt.
Kilowatts (kW) fit everyday use, like homes, motors, and small solar arrays.
Terawatts (TW) fit huge totals, like the output of many power plants combined.
It’s a power conversion.
Kilowatts and terawatts measure power (rate of energy use or production). Energy uses different units, like kilowatt-hours (kWh) or terawatt-hours (TWh).
No. Time doesn’t change a kW to TW conversion because both are power units.
Time matters when you convert energy, such as kWh to TWh.
Write the scale difference first: 1 TW = 10⁹ kW.
Then divide by 1,000,000,000 when going from kW to TW.
If your answer gets larger, the direction is wrong.
Use:
TW = kW × 10⁻⁹
Example:
500,000,000 kW = 5 × 10⁸ kW
5 × 10⁸ × 10⁻⁹ = 5 × 10⁻¹ = 0.5 TW
Multiply by 1,000,000,000:
kW = TW × 1,000,000,000
Example: 2.4 TW = 2.4 × 1,000,000,000 = 2,400,000,000 kW
