**Full name:** femtonewton

**Plural form:** femtonewtons

**Symbol:** fN

**Category type:** force

**Scale factor:** 1.0E-15

The SI derived unit for force is the newton.

1 newton is equal to 1.0E+15 femtonewton.

Valid units must be of the **force** type.

You can use this form to select from known units:

The SI prefix "femto" represents a factor of
10^{-15}, or in exponential notation, 1E-15.

So 1 femtonewton = 10^{-15} newtons.

The definition of a newton is as follows:

In physics, the newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work on classical mechanics. It was first used around 1904, but not until 1948 was it officially adopted by the General Conference on Weights and Measures (CGPM) as the name for the mks unit of force.
