Carabiner kN Rating Checker - Online Safety Converter

A 22 kN carabiner can withstand approximately 2,243 kg (4,945 lb) of static force before breaking. However, its safe working load (WLL) is much lower — usually 1/5 to 1/10 of the MBS, depending on the application. For climbing, dynamic falls can easily generate 5–12 kN, so a 22 kN rating provides a critical safety margin.

For personal fall protection and climbing, a safety factor of 10:1 is commonly recommended when calculating from static weight. Because actual loads in a fall are dynamic and can spike dramatically, the equipment’s high kN ratings already account for this. Always use gear certified to UIAA or CE standards and never exceed manufacturer limits.

kN measures force, not mass. Weight (kg or lb) depends on gravity, which varies slightly around the world. Force is an absolute measurement, making international safety standards more consistent. A 1 kg mass exerts roughly 0.0098 kN on Earth, so 22 kN ≈ 2,243 kg equivalent.

Yes, but be aware that dynamic ropes and slings absorb energy and reduce peak forces. The kN ratings on those items still indicate minimum breaking strength. This tool provides static conversions; consult your equipment’s manual for dynamic performance specifications.
