Ton-force is non-SI and best for large forces; femtonewton suits nanoscale forces
-
Conversions serve mainly theoretical and comparative purposes, not practical measurement
Frequently Asked Questions
-
What is a ton-force (metric)?
-
Ton-force (metric) is a non-SI unit of force equal to the force exerted by a mass of one metric tonne under standard gravity, equivalent to 9,806.65 newtons.
-
What is a femtonewton used for?
-
A femtonewton quantifies extremely small forces at the molecular and nanoscale, often used in precision measurements like biomolecular interactions and optical trapping.
-
Can this converter be used for precise experimental measurements?
-
The converter provides theoretical unit conversions mainly for data comparison purposes; direct experimental measurements require specialized high-precision instruments.
