What is a picowatt and where is it used?

A picowatt (pW) is a unit of power equal to 10^-12 watts, used to measure extremely small power levels such as in sensitive cryogenic detectors, microelectronics standby power, and faint astronomical signals.

How does millijoule per second relate to watts?

A millijoule per second (mJ/s) equals 0.001 joules per second, which is equivalent to 0.001 watts or 1 milliwatt, commonly used for low-power systems.

Why convert picowatt to millijoule/second?

Converting picowatt to millijoule/second helps relate tiny power amounts to more familiar units for interpreting and specifying power consumption in low-power electronics and experimental setups.

Tips & Best Practices

Ensure input values reflect accurate measurement sensitivity due to very small power scales
Interpret results carefully as millijoule/second units are typically used for higher power levels
Use significant figures appropriate to your measurement precision to avoid confusion
Refer to example conversions to verify correctness

Limitations

Picowatts represent extremely small power levels that can be near sensitivity limits
Millijoule/second is generally applied for somewhat larger powers, so conversions may require attention to precision and noise
Measurement noise can affect accuracy at these scales, so results should be interpreted cautiously
