The results are expressed in energy lost per unit of thickness (such as ft·lb/in or J/cm) at the notch. Alternatively, the results may be reported as energy lost per unit cross-sectional area at the notch (J/m 2 or ft·lb/in 2). In Europe, ISO 180 methods are used and results are based only on the cross-sectional area at the notch (J/m 2). The ...
J-toughness value signifies the resistance of the material in terms of amount of stress energy required for a crack to grow. J IC toughness value is measured for elastic-plastic materials. Now the single-valued J IC is determined as the toughness near the onset of the ductile crack extension (effect of strain hardening is not important). The ...
The J-integral represents a way to calculate the strain energy release rate, or work per unit fracture surface area, in a material. [1] The theoretical concept of J-integral was developed in 1967 by G. P. Cherepanov [2] and independently in 1968 by James R. Rice, [3] who showed that an energetic contour path integral (called J) was independent of the path around a crack.

The SI unit for specific energy is the joule per kilogram (J/kg). Other units still in use worldwide in some contexts are the kilocalorie per gram (Cal/g or kcal/g), mostly in food-related topics, and watt-hours per kilogram (W⋅h/kg) in the field of batteries.

This Wikipedia page provides a list of units of energy used in the template for converting measurements.
See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound.
