Kilojoules per millimeter to kilojoules per centimeter
Type a value in kJ/mm to get it in kJ/cm instantly.
12kJ/cm
That's 2× as hot as sheet metal welding, while structural welding is 1.25× higher. A 200 A, 25 V arc would have to travel about 200 mm a minute.
Convert the other way: kJ/cm to kJ/mm
What it means
How much heat goes in?
Heat input is arc energy times a process efficiency: about 0.8 for stick and MIG, 0.6 for TIG, and 1.0 for submerged arc.
The math
How to convert kJ/mm to kJ/cm
To convert kilojoules per millimeter to kilojoules per centimeter, multiply by 10.
Example: 1.2 kJ/mm × 10 = 12 kJ/cm.
In the other direction, 1 kJ/cm = 0.1 kJ/mm.
