How to Convert Piconewtons to Millinewtons

To convert piconewtons to millinewtons, multiply the force by the following conversion ratio: 1e-9 millinewtons/piconewton.

Since one piconewton is equal to 1e-9 millinewtons, you can use this simple formula to convert:

millinewtons = piconewtons × 1e-9

The force in millinewtons is equal to the force in piconewtons multiplied by 1e-9.

For example, here's how to convert 5 piconewtons to millinewtons using the formula above.

millinewtons = (5 pN × 1e-9) = 5e-9 mN

How Many Millinewtons Are in a Piconewton?

There are 1e-9 millinewtons in a piconewton, which is why we use this value in the formula above.

1 pN = 1e-9 mN|1 mN = 1,000,000,000 pN

Our piconewton to millinewton calculator automatically converts your force measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Piconewtons and millinewtons are both units used to measure force. Keep reading to learn more about each unit.

What Is a Piconewton?

A piconewton is a unit of force equal to 1/1,000,000,000,000 of a newton (1e-12 N). One-trillionth of a Newton. [1]

The piconewton is classified as a metric and SI-compatible unit of force. Piconewtons can be abbreviated as pN; for example, 1 piconewton can be written as 1 pN.

In the metric system, "pico" is the standard SI prefix for trillionths, or 10⁻¹². This makes the piconewton (pN) a convenient decimal multiple of the newton (N).

In practice, piconewtons (pN) are widely used across fine-tolerance laboratory, analytical, and micro-scale force measurements within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Millinewton?

A millinewton is a unit of force equal to 1/1,000 of a newton (0.001 N). One-thousandth of a Newton. [2]

The millinewton is classified as a metric and SI-compatible unit of force. Millinewtons can be abbreviated as mN; for example, 1 millinewton can be written as 1 mN.

In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millinewton (mN) a convenient decimal multiple of the newton (N).

In practice, millinewtons (mN) are widely used across fine-tolerance laboratory, analytical, and micro-scale force measurements within SI metric workflows, engineering documentation, and technical data sheets.

When converting force between piconewtons (pN) and millinewtons (mN), keep full floating-point precision (1 pN = 1e-9 mN; 1 mN = 1,000,000,000 pN) during intermediate calculations and round only the final millinewton figure to match your instrument tolerance.
