Value in terawatts per meter kelvin (TW/(m·K))

Use a decimal point, such as 2.5. Enter a value in TW/(m·K); the result is in ZW/(m·K).

Zettawatts per meter kelvin≈ 1e-9ZW/(m·K)

Formula

ZW/(m·K) ≈ TW/(m·K) × 1e-9

Worked example

Convert 1 TW/(m·K) to ZW/(m·K):

1 TW/(m·K) ≈ 1e-9 ZW/(m·K)

Multiply your TW/(m·K) value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What terawatts per meter kelvin measure

Terawatts per meter kelvin (TW/(m·K)) represent thermal conductivity. One unit equals 10^12 W/(m·K). Thermal conductivity relates heat flux to temperature gradient and is measured in watts per meter-kelvin.

Reading the result in zettawatts per meter kelvin

Zettawatts per meter kelvin (ZW/(m·K)) represent thermal conductivity. One unit equals 10^21 W/(m·K). Thermal conductivity relates heat flux to temperature gradient and is measured in watts per meter-kelvin.

Where this conversion helps

Normalize material conductivity specifications at the stated conditions. This is not thermal conductance or thermal resistance. Geometry and boundary conditions are needed to calculate heat flow.

How the scale changes

The input unit has a factor of 1e12 W/(m·K); the output unit has a factor of 1e21 W/(m·K). Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.

Reading very small or large results

Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
