To convert from Newton-meter (Nm) to Centinewton-meter (cNm), use the following formula:
Centinewton-meter (cNm)
= 100× Newton-meter (Nm)
Let's convert 5 Newton-meter (Nm) to Centinewton-meter (cNm).
Using the formula:
5 × 100 = 500
Therefore, 5 Newton-meter (Nm) is equal to 500 Centinewton-meter (cNm).
How many newton-meters are in one centinewton-meter? One Centinewton-meter (cNm) contains 0.01 Newton-meters (Nm) — the inverse of the factor above. Multiplying by 100 takes you from newton-meters to centinewton-meters; multiplying by 0.01 brings you back.
Put in words: one newton-meter equals 100 centinewton-meters, so the newton-meter is the larger 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.
A newton-meter (N·m) is the SI unit of torque — the twisting force that makes something rotate. One newton-meter is produced when a force of one newton acts at a perpendicular distance of one metre from the axis of rotation.
The distance matters as much as the force. Pushing on a spanner with 20 N at 0.5 m from the bolt gives 10 N·m. The same 20 N applied through a spanner twice as long gives 20 N·m — identical effort, double the turning effect. This is why a breaker bar loosens a bolt that a short wrench cannot.
The distance is always measured perpendicular to the line of the force. Pulling at an angle reduces the effective lever arm and therefore the torque.
Both work out to the same base units (kg·m²/s²), but they describe different things and must never be interchanged:
Standards keep them apart deliberately: energy is written in J, torque in N·m.
| Torque | Typical example |
|---|---|
| 5 N·m | bicycle stem bolt |
| 25 N·m | car spark plug |
| 110 N·m | car wheel nut |
| 400 N·m | family car engine peak |
A centinewton-meter (cN·m) is one hundredth of a newton-meter — a metric SI-prefixed unit for very small torques.
Some torques are genuinely tiny. A spectacle hinge screw, a watch case back or a miniature connector may need a fraction of a newton-meter. Writing 8 cN·m is clearer and safer on a specification than 0.08 N·m, where a missing zero changes the value tenfold.
Because centi is a plain SI prefix, the conversion is exact and involves no measurement standard — just a shift of the decimal point.
| From | To | Multiply by |
|---|---|---|
| cN·m | N·m | 0.01 |
| cN·m | lbf·in | 0.0885075 |
| cN·m | ozf·in | 1.41612 |
