Easy-to-Remember: Torque Conversion Table

Many of our professional customers will provide us with product drawings when they ask us to produce hand tools, and most of the drawings will indicate the torque value. However, for non-engineers or inexperienced users, it is not intuitive to judge the torque from the numerical size, because the torque units are different, for example, the common torque units are Nm, inch-pond, and kgf.cm.

In different countries, in different laboratories, you may see interesting combinations of torque units.

As we are Tool-Professiona-Maker, it is important to understand torque unit conversion and digital size sensitivity. But there are too many units. How to quickly and easily remember them?

In addition to downloading the torque unit conversion APP, a simple and good comparison torque table poster in your workshop or garage would be good for every man who likes DIY and loves his family. I would like to share below conversion torque unit table to all our industry friends for free.

Why Is It Important To Know The Torque of Hand Tools?

Torque is one of the most important specifications of hand tools. In order to understand why that is, we must first answer two key questions. What is torque? How is it measured?

Torque is the rotational equivalent of linear force. In physics, it is referred to as moment of force and indicates the tendency of a force to rotate the body to which it is applied. This concept originated with Archimedes’ investigation into levers.

In the diagram below, we see that torque equals length multiplied by force. Therefore, the farther from the object or axis you apply a given amount of force, the greater the torque.

Most fastening hand tools are intended to tighten and release bolts and nuts. Bolts and nuts are actually relatively fragile. If a user applies excessive torque, the nut or bolt is likely to break. That's why most auto-repair manuals indicate the maximum recommended torque for maintenance jobs.

On the other hand, if the user applies insufficient torque, the bolt will not be properly secured, and this is extremely dangerous. In automobiles or motorcycles, loose bolts may cause serious accidents. That's why Tien-I’s professional hand tools are designed to address the unique torque specifications of various applications.

The unit measurements of torque and conversions across various markets are shown in the table below.

European Standard : N-m

American Standard : ft-lb

Japan Standard : cm-kg

What is the difference between impact socket and chrome socket? Why is CR-V material not suitable at producing impact sockets?

Tien-i's hand sockets are made of Cr-V steel (CR-V).

Compared with the raw material "CR-V" for hand sockets, the raw material for pneumatic sockets, CR-MO, has stronger toughness, i.e. stronger shock resistance. Suitable for use with air and electric guns. CR-V steel (CR-V) has higher hardness, but in the need for shock-resistant use environment will lead to reduced service life.
