Length: The basic size of length should be familiar to everyone; here is the scientific definition anyway: The length indicates the extension of a physical object within one dimension.

Of course, you don’t need an engineering degree to convert between centimeters and meters. However, there are still said to be countries on this planet that are not convinced of the metric system - at this point a greeting to Chicago! That's why our tool naturally also allows you to convert from and to the imperial units of inches and feet.

Tension: It's essential for our steels, above all as a measure of their tensile strength; i.e. the maximum mechanical stress that a material can withstand in a tensile test.

In metric units, this value is given as Newtons per square millimeter (N/mm²), or Megapascals (MPa), because: 1 N/mm² = 1,000,000 PA = 1 MPa. Kilonewtons per square centimeter (kN/cm²) is also used for larger objects.

Of course, in the Anglo-American world, people are doing their own thing again. Pulling force is measured there in either kip-force per square inch (ksi) or pound-force per square inch (psi).

So you could now calculate how often you would have to lift a bar of chocolate to completely use up the energy it contained. For our materials, however, energy is more interesting in notched bar impact tests, which are used to determine the toughness of a material.

Our tool allows you to quickly convert in the joule space between joule (J), kilojoule (kJ) and dekajoule (daJ) and doesn't leave our American friends out in the rain either: the pound force times inch (in × lbf) is available to you as an additional one unit also available.
