500 Nm in pound-feet - how much is it?

    Three torque units, one tool. Convert Newton-meters to pound-feet, kg-m and back. Exact factors: 1 Nm = 0.7376 lb-ft, 1 lb-ft = 1.3558 Nm. Built for importing US/UK cars, comparing engine specs and reading service manuals.

    A torque of 500 Nm is one of the most commonly referenced values in automotive specs and service manuals. Whether you are comparing European and American engine data, setting a torque wrench for bolt tightening, or checking the output of an electric motor - this page converts 500 Newton-meters to pound-feet with the exact factor (0.737562) and shows where this torque sits among popular engines.

    Three units, one conversion - Nm, lb-ft and kg-m side by side

    A Mustang GT produces 420 lb-ft of torque. A BMW M3 delivers 550 Nm. Which one has more twist? Without converting, you cannot tell. The answer: the BMW wins with 550 Nm vs 569 Nm (420 lb-ft converted). This converter handles all three torque units used in automotive engineering - Newton-meters, pound-feet and the legacy kilogram-meter.

    How to convert torque - step by step

    1. Select conversion direction - pick which units you are converting from and to. Four options: Nm to lb-ft, lb-ft to Nm, Nm to kg-m, kg-m to Nm.
    2. Enter the torque value - type the number from your spec sheet, service manual or torque wrench. The input field adjusts to the selected direction.
    3. Read the result - the converted value appears instantly with the exact formula and a step-by-step calculation breakdown.

    From To Multiply by Example
    Nm lb-ft 0.737562 300 Nm = 221.27 lb-ft
    lb-ft Nm 1.35582 300 lb-ft = 406.75 Nm
    Nm kg-m 0.101972 300 Nm = 30.59 kg-m

    Practical examples

    Importing a US-spec car: The Dodge Charger SRT produces 485 lb-ft. In Nm: 485 x 1.35582 = 657.6 Nm. For reference, a Mercedes-AMG C63 S produces 680 Nm.
    Torque wrench setting: Wheel lug nuts spec says 110 Nm. Your wrench reads lb-ft only. 110 x 0.7376 = 81.1 lb-ft. Set your wrench to 81.
    Vintage car manual: A 1970s Fiat manual lists engine torque as 12.5 kg-m. In modern units: 12.5 x 9.80665 = 122.6 Nm (about the same as a modern 1.0 turbo engine).
    Comparing turbo vs NA: A turbocharged 2.0L produces 350 Nm at 1,500 RPM. A naturally aspirated 3.5L produces 310 Nm at 4,600 RPM. In lb-ft: 258 vs 229. The turbo wins on low-end torque despite smaller displacement.
    Diesel vs petrol: A 2.0 diesel at 400 Nm (295 lb-ft) vs a 2.0 petrol at 250 Nm (184 lb-ft). The diesel delivers 60% more torque at lower RPM, which is why it feels stronger for towing and overtaking.

    FAQ - Frequently asked questions

    What is the difference between torque and horsepower?
    Torque is rotational force - how hard the engine twists the crankshaft. Horsepower is the rate of work - torque multiplied by RPM. A diesel engine may have high torque but low horsepower because it produces maximum twist at low RPM. A sports car engine may have moderate torque but high horsepower because it spins to 8,000+ RPM. Formula: HP = Torque (Nm) x RPM / 5,252.
    Why do US cars list torque in lb-ft instead of Nm?
    The United States uses the Imperial system. Pound-foot (lb-ft) measures force in pounds applied at a distance of one foot from the pivot point. Europe adopted SI units (Newton-meters) as the international standard. Japan uses Nm as well. The UK uses both systems depending on the manufacturer - British-designed cars use Nm, while US imports retain lb-ft.
    Is lb-ft the same as ft-lbs?
    In common usage, yes - both refer to the same unit. Technically, lb-ft (pound-foot) is the correct engineering notation for torque, while ft-lb (foot-pound) is the unit of energy/work. Most automotive sources use them interchangeably, but if precision matters, use lb-ft for torque.
    How do I read torque specs for bolt tightening?
    Service manuals specify torque in Nm or lb-ft for each bolt. Set your torque wrench to the exact value. Common examples: wheel lug nuts 100-120 Nm (74-89 lb-ft), spark plugs 20-30 Nm (15-22 lb-ft), oil drain plug 25-35 Nm (18-26 lb-ft). Over-tightening strips threads. Under-tightening causes parts to loosen.
    What is a good torque figure for a family car?
    A comfortable family car delivers 200-350 Nm (148-258 lb-ft). Below 200 Nm feels sluggish with passengers and luggage. Above 350 Nm is sporty territory. For towing, look for 400+ Nm (295+ lb-ft) from a diesel or turbocharged engine. Electric cars often exceed 500 Nm because electric motors deliver maximum torque from zero RPM.
    Why is kg-m still used in some countries?
    The kilogram-meter (kg-m or kgf-m) was the standard metric torque unit before the SI system was adopted in 1960. You still find it in older Japanese car manuals, vintage European specifications and some industrial equipment documentation. The conversion is simple: 1 kg-m = 9.80665 Nm (gravitational acceleration constant).
