What is a Kilocalorie per Hour and a Foot-pound per Minute?

1 kcal/h = 1.163 W = 0.001163 kW = 0.00156 hp = 3.968 BTU/h = 4,184 J/h

Note: Uses food Calorie (Cal) = kilocalorie (kcal) = 1,000 small calories

1 ft⋅lbf/min = 0.0226 W = 0.0000226 kW = 0.00003 hp = 0.0771 BTU/h

Horsepower relationship: 33,000 ft⋅lbf/min = 1 hp (745.7 W) exactly

Note: The Kilocalorie per Hour is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Foot-pound per Minute belongs to the imperial/US customary system.

Common Uses and Applications: kcal/h vs ft⋅lb/min

Explore the typical applications for both Kilocalorie per Hour (imperial/US) and Foot-pound per Minute (imperial/US) to understand their common contexts.

Common Uses for kcal/h

Metabolism: Basal metabolic rate (BMR), daily energy expenditure. Nutrition: Energy requirements, dietary planning. HVAC: Human body heat load in building calculations (Europe). Sports Science: Exercise energy expenditure, training zones.

When to Use ft⋅lb/min

Historical: Original horsepower definition (Watt, 1780s). Engineering Education: Teaching power unit derivations. Rarely Used: Impractically small for modern applications. Conversion Reference: Link between hp and ft⋅lbf/s.

Additional Unit Information

About Kilocalorie per Hour (kcal/h)

How do I convert kcal/h to watts?

Formula: W = kcal/h × 1.163

Examples:

  • 60 kcal/h = 70 W (sleeping)
  • 100 kcal/h = 116 W (sitting)
  • 500 kcal/h = 582 W (running)
  • 1,000 kcal/h = 1,163 W = 1.16 kW

kcal/h to Watts converter →

How do I calculate my basal metabolic rate (BMR)?

Mifflin-St Jeor Equation (most accurate):

Men: BMR (kcal/day) = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) + 5 Women: BMR (kcal/day) = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) - 161

Convert to kcal/h: Divide by 24

Example - 30-year-old male, 80kg, 180cm:

  • BMR = (10 × 80) + (6.25 × 180) - (5 × 30) + 5 = 1,730 kcal/day
  • Hourly rate: 1,730 ÷ 24 = 72 kcal/h = 84 W

Example - 30-year-old female, 65kg, 165cm:

  • BMR = (10 × 65) + (6.25 × 165) - (5 × 30) - 161 = 1,370 kcal/day
  • Hourly rate: 1,370 ÷ 24 = 57 kcal/h = 66 W

What is the difference between kcal/h and cal/s?

kcal/h = Kilocalories per hour (large Calorie per hour) cal/s = Calories per second (small calorie per second)

Conversion: 1 cal/s = 3.6 kcal/h

Usage:

  • kcal/h: Metabolism, nutrition (aligns with daily calorie counts)
  • cal/s: Physics, thermodynamics

Example: 100W power

  • As watts: 100 W
  • As kcal/h: 86 kcal/h
  • As cal/s: 24 cal/s

How many kcal/h do I burn exercising?

MET (Metabolic Equivalent) method:

Formula: kcal/h = MET × weight(kg) × 1.05

Common MET values:

  • Sleeping: 0.9 METs
  • Sitting: 1.0 METs
  • Walking (3 mph): 3.5 METs
  • Jogging (5 mph): 8.0 METs
  • Running (7 mph): 11.5 METs
  • Cycling (moderate): 8.0 METs
  • Swimming (moderate): 8.0 METs

Example - 70kg person running at 7 mph:

  • kcal/h = 11.5 × 70 × 1.05 = 845 kcal/h = 982 W

Example - 70kg person walking at 3 mph:

  • kcal/h = 3.5 × 70 × 1.05 = 257 kcal/h = 299 W

Why does HVAC use kcal/h in some countries?

Historical: European HVAC tradition used kcal/h before SI adoption Body heat: Natural unit for human heat output (matches food calories) Transition: Many European countries now use watts Mixed practice: Some European standards still reference kcal/h

Conversion for HVAC:

  • 1 person (seated): 100 kcal/h = 116 W
  • Conference room (20 people): 2,000 kcal/h = 2,320 W = 2.32 kW
  • Gym (50 people, active): 20,000 kcal/h = 23,200 W = 23.2 kW

Modern practice: Most HVAC calculations now in watts or BTU/h.

About Foot-pound per Minute (ft⋅lb/min)

How do I convert ft⋅lbf/min to horsepower?

Formula: hp = ft⋅lbf/min ÷ 33,000

Examples:

  • 33,000 ft⋅lbf/min = 1 hp (exact)
  • 16,500 ft⋅lbf/min = 0.5 hp
  • 66,000 ft⋅lbf/min = 2 hp
  • 330,000 ft⋅lbf/min = 10 hp

ft⋅lbf/min to HP converter →

How do I convert ft⋅lbf/min to ft⋅lbf/s?

Formula: ft⋅lbf/s = ft⋅lbf/min ÷ 60

Examples:

  • 60 ft⋅lbf/min = 1 ft⋅lbf/s
  • 600 ft⋅lbf/min = 10 ft⋅lbf/s
  • 33,000 ft⋅lbf/min = 550 ft⋅lbf/s = 1 hp

ft⋅lbf/min to ft⋅lbf/s converter →

Why 33,000 ft⋅lbf/min for 1 hp?

James Watt's experiment (1780s):

Observation: Draft horses in coal mines

  • Work rate: Lifting ~22,000 lb⋅ft/min (typical horse)
  • Watt's definition: 33,000 ft⋅lbf/min (50% above average)
  • Marketing: Sell steam engines rated conservatively vs horses

Calculation:

  • 33,000 ft⋅lbf/min ÷ 60 = 550 ft⋅lbf/s
  • 550 ft⋅lbf/s × 1.356 = 745.7 W (modern equivalent)

Persists: Still defines horsepower 240+ years later!

How do I calculate power in ft⋅lbf/min?

Formula: Power (ft⋅lbf/min) = Force (lbf) × Distance per minute (ft/min)

Examples:

  • Lifting 100 lb at 10 ft/min: 1,000 ft⋅lbf/min = 0.03 hp = 22.6 W
  • Winch pulling 500 lb at 20 ft/min: 10,000 ft⋅lbf/min = 0.3 hp = 226 W
  • Elevator lifting 2,000 lb at 100 ft/min: 200,000 ft⋅lbf/min = 6.06 hp = 4.52 kW

Modern practice: Convert to hp or kW for practical use.
