Impact Strength Converter Formulas
J/m² to ft·lbf/in²
ft·lbf/in² = J/m² ÷ 1355.818
Example: 1000 J/m² = 1000 ÷ 1355.818 = 0.738 ft·lbf/in²
ft·lbf/in² to J/m²
J/m² = ft·lbf/in² × 1355.818
Example: 0.5 ft·lbf/in² = 0.5 × 1355.818 = 677.9 J/m²
J/m² to kJ/m²
kJ/m² = J/m² ÷ 1000
Example: 2500 J/m² = 2500 ÷ 1000 = 2.5 kJ/m²
kJ/m² to J/m²
J/m² = kJ/m² × 1000
Example: 3.2 kJ/m² = 3.2 × 1000 = 3200 J/m²

Frequently Asked Questions
What is impact strength in material testing?
Impact strength measures how much energy a material can absorb before breaking. It is tested using Charpy test or Izod test methods. Our impact strength converter helps convert between different units easily.
How do I convert J/m² to ft·lbf/in²?
To convert Joule per square meter to foot-pound per square inch, divide by 1355.818. For example: 1000 J/m² ÷ 1355.818 = 0.738 ft·lbf/in². This material testing calculator does this math automatically.
What is the difference between Charpy and Izod tests?
Charpy test and Izod test are both impact strength tests. Charpy test uses a horizontal sample, while Izod test uses a vertical sample. Both measure impact energy in similar units that our impact strength converter handles.
