The SI prefix "atto" represents a factor of
10^{-18}, or in exponential notation, 1E-18.

So 1 attonewton = 10^{-18} 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.

The SI prefix "zepto" represents a factor of
10^{-21}, or in exponential notation, 1E-21.

So 1 zeptonewton = 10^{-21} 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.
