The Impact Energy Conversion Calculator allows quick and accurate conversion between joules (J) and foot‑pounds (ft‑lb), units commonly used to report Charpy V‑Notch impact test results. Frequently referenced in API, ASTM, and project specifications, this tool helps engineers, inspectors, and buyers easily interpret mill test report data and compare impact requirements across metric and imperial standards. By simplifying unit conversion, the calculator supports material verification, low‑temperature service evaluation, and compliance with project specifications.

Joules to Ft/LBS:
Joules / 1.35582 = ft-lbs
