What does a picowatt measure?

A picowatt measures power at the scale of one trillionth of a watt, indicating extremely low levels of energy transfer.

How is joule/hour related to watts?

One joule per hour equals one divided by 3600 watts, making it a smaller measure of power over time.

Why convert picowatts to joules per hour?

It helps express tiny instantaneous power levels as energy transferred over hours, useful for low-power applications.

What Is This Tool?

This tool allows you to convert power measurements from picowatts (pW), which represent extremely small power levels, to joules per hour (J/h), a unit expressing energy transfer over time. It is designed to assist in interpreting sensitive power data across scientific and engineering fields.

How to Use This Tool?

Enter the value in picowatts (pW) you wish to convert.
Select picowatt as the input unit and joule/hour as the output unit.
Click the convert button to see the equivalent power expressed in joules per hour.
Use the result to analyze low-level power transfer over long periods.

Key Features

Converts picowatt units to joule per hour values using the exact conversion factor.
Browser-based and easy to use without requiring additional software.
Suitable for analyzing low-power or long-duration energy transfer rates.
Supports applications in cryogenics, ultra-low-power electronics, and thermal experiments.

Examples

Convert 5 picowatts: 5 × 3.6e-9 = 1.8e-8 joule/hour
Convert 100 picowatts: 100 × 3.6e-9 = 3.6e-7 joule/hour

Common Use Cases

Measuring noise or signal power in cryogenic and quantum sensors.
Assessing leakage or standby power in ultra-low-power microelectronics and IoT devices.
Analyzing faint astronomical signals and quantum-device outputs.
Evaluating slow thermal losses or heat output in laboratory setups.

Tips & Best Practices

Ensure input values are measured accurately with sensitive instruments.
Interpret joule/hour results within the context of longer-duration energy transfer.
Use this conversion to compare very small instantaneous power levels as energy rates over hours.
Be cautious with rapid power changes as the unit averages energy over time.

Limitations

Conversion assumes steady power transfer over one hour; it may not capture fast fluctuations.
Requires precise measurements due to extremely small power values involved.
Joule/hour is less commonly used than watt and may require careful interpretation.
