In 1 dynes there are 1.01972e-9 tonne-force. Meanwhile in 1 tonne-force there are 980,665,000 dynes. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Tonne-force to Dynes calculator above to convert any number.

To convert dynes (dyn) to tonne-force (tf), convert through newtons (N).
So the direct dyne to tonne-force conversion is:
The reverse tonne-force to dyne conversion is:
Example:
A dyne (dyn) is a unit of force in the CGS system (centimeter-gram-second). One dyne is the force needed to accelerate 1 gram at 1 centimeter per second squared. It’s a small unit, so it’s often used for tiny forces.
A tonne-force (tf) is a unit of force based on the weight of a 1-tonne mass under standard gravity. It is also written as metric ton-force or ton-force (metric). It’s common in engineering and load ratings.
To convert dynes to tonne-force, use this relationship:
The direct formula is:
There are:
One dyne equals:
Yes. This method helps if you already work in SI units:
Example:
No. Tonne-force is force, and tonne is mass.
A 1-tonne mass creates about 1 tf of force only under standard gravity. If gravity changes, the force changes too.
The dyne is defined from mass and acceleration, so it’s fixed. Tonne-force is tied to standard gravity, so the conversion uses g₀ = 9.80665 m/s². If you use a different gravity value, the force in “tonne-force” terms can shift.
Common symbols are:
They are not the same:
The Calculate Box tool to convert dynes to tonne-force uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a dynes value in the box and have it instantly converted to tonne-force.
