terapascal to millipascal

Convert terapascal (TPa) to millipascal (mPa). Use an editable pressure converter, conversion formula, and reference table.

1e+15

1 TPa = 1e+15 mPa

Calculated in your browser

Conversion formula

mPa = TPa × 1e+15

One terapascal equals 1e+15 millipascal. Multiply your value in terapascal by this factor to get millipascal. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 terapascal:
5 × 1e+15 = 5e+15 mPa

About these measurements

Pressure is force per unit of area.

The base reference used here is the pascal. One terapascal is 1e+12 base units; one millipascal is 0.001 base units.

Important distinctions

Gauge and absolute pressures must not be mixed. This converts units without changing the reference pressure.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert TPa to mPa?

Multiply the quantity in TPa by 1e+15. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the millipascal to terapascal converter.
