One dyne is exactly 0.01 millinewtons, so converting dynes to millinewtons 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.
One thousandth of a newton — the range of surface tension and small actuators. 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 millinewtons, which is usually more useful than the bare number.
The formula
dynes- The amount you are converting, in dynes
0.01- The exact number of millinewtons in one dyne
millinewtons- The converted result
How it works, step by step
- Enter the value in dynes.
- It is multiplied by 0.01, the exact factor between the two units.
- The answer is shown in millinewtons, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Lifting a bag of sugar: 9.81e+05 dyn in millinewtons
Lifting a bag of sugar comes to about 9.81e+05 dyn. Multiplying by the factor: 9.81e+05 × 0.01 = 9810 mN. Dividing the answer back by 0.01 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A sheet of paper’s weight: 4900 dyn in millinewtons
At 4900 dyn (a sheet of paper’s weight), the same quantity in millinewtons is 4900 × 0.01 = 49 mN. One dyne is 0.01 millinewtons, so the numbers shrink as expected.

Frequently asked questions
How many millinewtons are in one dyne?
Exactly 0.01. 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 millinewtons?
millinewtons = dynes × 0.01. Reversed, dynes = millinewtons ÷ 0.01, which is the same as multiplying by 100.
Which is the bigger unit, the dyne or the millinewton?
The millinewton. One dyne is only 0.01 of a millinewton, so it takes 100 dynes to make one millinewton.
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 millinewton?
One thousandth of a newton — the range of surface tension and small actuators.
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.
