      "q": "What is the formula to convert kilogram-force meters to newton-meters?",
      "a": "Multiply the value in kilogram-force meters by 9.80665: newton-meters = kilogram-force meters × 9.80665. For example, 5 kgf·m = 49.0332 N·m."

      "q": "How do I convert newton-meters back to kilogram-force meters?",
      "a": "Multiply by the inverse factor 0.1019716213 (kilogram-force meters = newton-meters × 0.1019716213), or use the newton-meters-to-kilogram-force meters page."
