Convert Torque from Ounce-inches to Decinewton-meters (ozf-in to dNm)

Ounce-inch to Decinewton-meter Conversion Formula

Example

Let's convert 5 Ounce-inch (ozf-in) to Decinewton-meter (dNm).

Using the formula:

Therefore, 5 Ounce-inch (ozf-in) is equal to 0.35307759999225961905 Decinewton-meter (dNm).

How many ounce-inches are in one decinewton-meter? One Decinewton-meter (dNm) contains 14.161192893883987621 Ounce-inches (ozf-in) — the inverse of the factor above. Multiplying by 0.07061551999845192381 takes you from ounce-inches to decinewton-meters; multiplying by 14.161192893883987621 brings you back.

Put in words: one ounce-inch equals 0.07061551999845192381 decinewton-meters, so the ounce-inch 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 an Ounce-inch (ozf·in)?

An ounce-inch (ozf·in) is one ounce-force applied at one inch from the axis — the smallest of the common imperial torque units.

• 1 lbf·in = 16 ozf·in
• 1 lbf·ft = 192 ozf·in
• 1 ozf·in = 0.00706155 N·m

The Unit of Small Motors

Ounce-inches exist because small electric motors produce tiny torques that would be unreadable in pound-feet. A stepper motor rated at 0.35 lbf·ft is far more naturally described as 67 ozf·in, and that is how manufacturers publish it.

If you are choosing a stepper or servo for a 3D printer, CNC machine or robot, the datasheet holding-torque figure will almost certainly be in ozf·in or in N·cm.

Where Ounce-inch Is Used

• Stepper and servo motors — holding torque and detent torque ratings.
• Small gearmotors in appliances, printers and automation.
• Watchmaking and instrument work — miniature screws.
• Torque testing of caps, closures and small assemblies.

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.
