What is a Calorie per Second and a Foot-pound per Minute?

1 cal/s = 4.184 W = 0.004184 kW = 0.0056 hp = 14.29 BTU/h

Note: This uses IT (International Table) calorie = 4.1868 J (standard)

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 Calorie per Second 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: cal/s vs ft⋅lb/min

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

Common Uses for cal/s

Physics Education: Thermodynamics problems, heat transfer calculations. Older Literature: Pre-SI engineering texts, vintage HVAC data. Scientific: Some chemistry and biology applications. Rarely Modern: Watts or kilocalories per hour preferred today.

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 Calorie per Second (cal/s)

How do I convert cal/s to watts or kW?

Formula:

  • W = cal/s × 4.184
  • kW = cal/s × 0.004184

Examples:

  • 1 cal/s = 4.184 W
  • 10 cal/s = 41.84 W
  • 100 cal/s = 418.4 W = 0.418 kW
  • 1,000 cal/s = 4,184 W = 4.184 kW

cal/s to Watts converter → cal/s to kW converter →

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

cal/s = Small calorie per second (rapid power) kcal/h = Kilocalorie (food Calorie) per hour (slower rate)

Conversion: 1 cal/s = 3.6 kcal/h

Usage:

  • cal/s: Physics, instant power measurements
  • kcal/h: Metabolism, HVAC (some regions)

Example: 70W human at rest

  • As watts: 70 W
  • As cal/s: 16.7 cal/s
  • As kcal/h: 60 kcal/h

How do I calculate heat transfer in cal/s?

Formula: Power (cal/s) = Heat (cal) ÷ Time (s)

Example: Melting ice

  • Ice mass: 100 g
  • Heat needed: 8,000 cal (80 cal/g latent heat)
  • Time: 60 seconds
  • Power: 8,000 ÷ 60 = 133 cal/s = 558 W

Heating water:

  • Water: 1 kg (1,000 g)
  • Temperature rise: 10°C
  • Heat needed: 10,000 cal (1 cal/g⋅°C × 1,000g × 10°C)
  • Time: 100 seconds
  • Power: 10,000 ÷ 100 = 100 cal/s = 418 W

Why use watts instead of cal/s?

SI standard: Watts are internationally standardized (1 W = 1 J/s) Simpler: Avoids cal vs kcal vs Cal confusion Electrical: All electrical power in watts Universal: Works across all energy forms (mechanical, electrical, thermal)

Exception: Some nutrition/metabolism research still uses cal/s or kcal/h for historical consistency.

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.
