One dyne is exactly 0.001019716213 grams-force, so converting dynes to grams-force is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
The weight of one gram at standard gravity, used for keyboard switches, sutures and fibre testing. The CGS unit of force, equal to 10 micronewtons.
Mass is not force. A kilogram is a mass; a kilogram-force is the weight of that mass at standard gravity, 9.80665 N. Bathroom scales blur the distinction because they are calibrated for Earth; engineering calculations cannot. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into grams-force, which is usually more useful than the bare number.
The formula
dynes- The amount you are converting, in dynes
0.00101971621298- The exact number of grams-force in one dyne
grams-force- The converted result
How it works, step by step
- Enter the value in dynes.
- It is multiplied by 0.00101971621298, the exact factor between the two units.
- The answer is shown in grams-force, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A sheet of paper’s weight: 4900 dyn in grams-force
Take a sheet of paper’s weight, roughly 4900 dyn. The conversion is a single multiplication — 4900 × 0.00101972 — giving 4.99661 gf. Because the relationship is proportional, doubling the input doubles the answer to 9.99322 gf.
Lifting a bag of sugar: 9.81e+05 dyn in grams-force
Take lifting a bag of sugar, roughly 9.81e+05 dyn. The conversion is a single multiplication — 9.81e+05 × 0.00101972 — giving 1000.34 gf. Because the relationship is proportional, doubling the input doubles the answer to 2000.68 gf.

Frequently asked questions
How many grams-force are in one dyne?
Exactly 0.00101971621298. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert dynes to grams-force?
grams-force = dynes × 0.00101971621298. Reversed, dynes = grams-force ÷ 0.00101971621298, which is the same as multiplying by 980.665.
Which is the bigger unit, the dyne or the gram-force?
The gram-force. One dyne is only 0.00101972 of a gram-force, so it takes 980.665 dynes to make one gram-force.
What does this quantity actually measure?
Both units measure force. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a dyne?
The CGS unit of force, equal to 10 micronewtons.
What is a gram-force?
The weight of one gram at standard gravity, used for keyboard switches, sutures and fibre testing.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do dyn to gf in my head?
Plenty of people do this in their head: divide by 1000 instead of using the exact factor 0.001019716213. At 100 that shortcut gives 0.1 grams-force, off by 0.001972 grams-force or about 1.93%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
