If a torque wrench setting is 50 ft-lb, what is the equivalent in inch-lb?

• A. 600
• B. 50
• C. 20
• D. 1000

Answer: (A)

When converting torque from foot-pounds to inch-pounds, use that 1 foot equals 12 inches. So the inch-pound value is 12 times the foot-pound value. For 50 ft-lb, that’s 50 × 12 = 600 in-lb. The other numbers don’t fit because they don’t apply the 12-inch-per-foot relationship (they’d either ignore the conversion or apply a different multiplier).
