Convert Torque from Kilogram-centimeters to Decinewton-meters (kg-cm to dNm)

Kilogram-centimeter to Decinewton-meter Conversion Formula

Example

Let's convert 5 Kilogram-centimeter (kg-cm) to Decinewton-meter (dNm).

Using the formula:

Therefore, 5 Kilogram-centimeter (kg-cm) is equal to 4.9033249998938675 Decinewton-meter (dNm).

How many kilogram-centimeters are in one decinewton-meter? One Decinewton-meter (dNm) contains 1.0197162130000000063 Kilogram-centimeters (kg-cm) — the inverse of the factor above. Multiplying by 0.9806649999787735 takes you from kilogram-centimeters to decinewton-meters; multiplying by 1.0197162130000000063 brings you back.

Put in words: one kilogram-centimeter equals 0.9806649999787735 decinewton-meters, so the kilogram-centimeter is the smaller unit of this pair. Converting between them never changes the amount of torque being measured — only the size of the unit you count it in.

What Is a Kilogram-centimeter (kgf·cm)?

A kilogram-centimeter (kgf·cm) is one kilogram-force acting at one centimetre from the axis. It is one hundredth of a kilogram-meter.

• 1 kgf·cm = 0.0980665 N·m
• 1 kgf·m = 100 kgf·cm

The Hobby Servo Unit

If you have ever bought a hobby servo, you have seen this unit. Servo torque is published almost universally in kgf·cm — a common 9 g micro servo is rated around 1.8 kgf·cm, a standard-size servo around 10–20 kgf·cm.

The rating tells you how much weight the servo can hold at a given arm length: 10 kgf·cm means it can just support 10 kg at 1 cm from the shaft, or 1 kg at 10 cm, or 0.5 kg at 20 cm. Doubling the arm halves the load it can hold.

Where Kilogram-centimeter Is Used

• RC servos and hobby robotics — the dominant unit in datasheets and marketplaces.
• Small gearmotors sold through electronics suppliers.
• Legacy metric torque specifications for small fasteners.
• Tyre valve and small assembly torque figures on older equipment.

What Is a Decinewton-meter (dN·m)?

A decinewton-meter (dN·m) is one tenth of a newton-meter.

• 1 dN·m = 0.1 N·m
• 1 N·m = 10 dN·m

A Narrow but Real Use

The decinewton-meter sits between the newton-meter and the centinewton-meter, and it is the least common of the three. Where it does appear, it is usually because a measuring instrument's range happens to fall there and whole numbers read more cleanly than decimals.

Its most established use is in rubber and polymer testing: the torque curves produced by a moving-die rheometer are conventionally plotted in dN·m, and the standard test reports quote minimum and maximum torque in that unit.

Where Decinewton-meters Are Used

• Rubber rheometry — cure curves under ASTM D5289 and related standards.
• Materials laboratories reporting small torque measurements.
• Some torque measurement instruments with a dN·m display range.

Because deci is a plain SI prefix, conversion is an exact decimal shift.
