What is a Erg per Second and a BTU per Minute?

1 erg/s = 10^-7 W = 0.0000001 W = 0.0000000001 kW

Erg definition: 1 erg = 1 dyne⋅cm = 10^-7 joules

1 BTU/min = 17.58 W = 0.01758 kW = 60 BTU/h = 0.0236 hp = 1.055 kJ/min

Note: The Erg per Second is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The BTU per Minute belongs to the imperial/US customary system.

Common Uses and Applications: erg/s vs BTU/min

Explore the typical applications for both Erg per Second (imperial/US) and BTU per Minute (imperial/US) to understand their common contexts.

Common Uses for erg/s

Astrophysics: Stellar luminosity, cosmic ray power, radiation output. Older Literature: Pre-1960 physics textbooks, historical research. Spectroscopy: Radiation intensity in some fields. Academic: Teaching unit systems, dimensional analysis.

When to Use BTU/min

Industrial Burners: Gas burners, process heaters (sometimes rated in BTU/min). Engineering: Conversion reference between BTU/h and BTU/s. Boilers: Small commercial boilers (though BTU/h more common). Rarely Used: Most applications use BTU/h or kW instead.

Additional Unit Information

About Erg per Second (erg/s)

How do I convert erg/s to watts?

Formula: W = erg/s × 10^-7 (or erg/s ÷ 10,000,000)

Examples:

  • 10^7 erg/s = 1 W
  • 10^8 erg/s = 10 W
  • 10^10 erg/s = 1,000 W = 1 kW
  • 10^13 erg/s = 1,000,000 W = 1 MW

erg/s to Watts converter →

Why do astrophysicists use erg/s for stars?

Historical: Astrophysics literature established with CGS units (pre-1960) Large numbers: 10^33 erg/s easier to write than 10^26 W in some contexts Convention: Astronomical journals still accept erg/s Transition: Modern papers increasingly use watts or solar luminosity units

Solar luminosity unit (L☉):

  • 1 L☉ = 3.828 × 10^26 W = 3.828 × 10^33 erg/s

Example: Sirius = 25 L☉ = 9.7 × 10^27 W = 9.7 × 10^34 erg/s

How do I convert between erg/s and J/s (watts)?

Relationship: 1 erg = 10^-7 joules

Therefore: 1 erg/s = 10^-7 J/s = 10^-7 W

Examples:

  • 10,000,000 erg/s = 1 J/s = 1 W
  • 10^10 erg/s = 1,000 J/s = 1 kW
  • 3.828 × 10^33 erg/s = 3.828 × 10^26 W (Sun)

What is the Sun's power output?

In different units:

  • Watts: 3.828 × 10^26 W
  • erg/s: 3.828 × 10^33 erg/s
  • Joules/s: 3.828 × 10^26 J/s
  • Horsepower: 5.13 × 10^23 hp

Perspective:

  • Earth receives: ~1.74 × 10^17 W (1.74 × 10^24 erg/s)
  • Only ~0.00000005% of Sun's total output
  • Sun converts ~4 million tons of mass to energy per second (E=mc²)

Why transition from CGS to SI units?

SI advantages:

  • Universal: Works across all fields (not just mechanics)
  • Electrical compatibility: Watts naturally link mechanical and electrical power
  • Simpler prefixes: kW, MW, GW easier than 10^10, 10^13, 10^16 erg/s
  • International standard: Adopted globally since 1960

CGS still used: Some specialized fields (astrophysics, Gaussian units for E&M)

Modern trend: Even astrophysics journals increasingly accept SI units (watts, joules).

About BTU per Minute (BTU/min)

How do I convert BTU/min to BTU/h?

Formula: BTU/h = BTU/min × 60

Examples:

  • 100 BTU/min = 6,000 BTU/h
  • 1,000 BTU/min = 60,000 BTU/h
  • 10,000 BTU/min = 600,000 BTU/h

BTU/min to BTU/h converter →

How do I convert BTU/min to watts or kW?

Formula:

  • W = BTU/min × 17.58
  • kW = BTU/min × 0.01758

Examples:

  • 100 BTU/min = 1,758 W = 1.76 kW
  • 1,000 BTU/min = 17,580 W = 17.58 kW
  • 5,000 BTU/min = 87,900 W = 87.9 kW

BTU/min to Watts converter → BTU/min to kW converter →

Why is BTU/min rarely used?

BTU/h preferred: Easier to work with for HVAC sizing (avoid large numbers) kW preferred: International standard, simpler calculations BTU/min awkward: Falls between BTU/h (too slow) and BTU/s (too fast)

Example comparisons:

  • BTU/h: 100,000 BTU/h (easy to read)
  • BTU/min: 1,667 BTU/min (awkward decimal)
  • kW: 29.3 kW (simple)

Most equipment nameplates use BTU/h or kW, not BTU/min.
