What is a Kilogram-force per Square Centimeter and a Atmosphere?

1 kgf/cm² = 98,066.5 Pa = 98.0665 kPa = 0.980665 bar = 0.0981 MPa = 14.2233 PSI = 0.9678 atm

Also written as: kg/cm², at (technical atmosphere), kgf/cm2, kg-f/cm²

Physical meaning: Pressure exerted by 1 kilogram-force over 1 square centimeter

1 atm = 101,325 Pa = 101.325 kPa = 14.696 PSI = 1.01325 bar = 760 mmHg = 760 Torr = 29.92 inHg

Why "Atmosphere"?

The atmosphere unit is uniquely important because:

  • Defined exactly: CIPM (1954) set 1 atm = 101,325 Pa (exact)
  • Sea level reference: Based on average atmospheric pressure (not variable)
  • Universal constant: Used identically worldwide (unlike PSI or bar)
  • Chemistry standard: All chemistry/physics equations reference 1 atm conditions
  • STP baseline: "Standard Temperature and Pressure" = 0°C, 1 atm exactly

Note: The Kilogram-force per Square Centimeter is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Atmosphere belongs to the imperial/US customary system.

Common Uses and Applications: kilograms-force per square centimeter vs atmospheres

Explore the typical applications for both Kilogram-force per Square Centimeter (imperial/US) and Atmosphere (imperial/US) to understand their common contexts.

Common Uses for kilograms-force per square centimeter

Older Engineering: Equipment specifications from pre-1980s. Hydraulics: Older hydraulic systems (Europe, Asia). HVAC: Refrigeration pressures (some regions). Asian Industries: Still common in China, India, Japan for some applications.

When to Use atmospheres

Chemistry: Gas laws (PV=nRT), reaction conditions, vapor pressures, standard conditions (STP).

  • Ideal Gas Law: P V = n R T (pressures typically in atm in chemistry)
  • Gas tables: Vapor pressures often given at 1 atm
  • STP (Standard Temperature & Pressure): Exactly 1 atm, 0°C (sometimes 25°C modern definition)

Diving: Depth pressure calculations (1 atm per 10m/33ft water).

  • Critical for: Decompression sickness risk, nitrogen narcosis, oxygen toxicity
  • Rule of thumb: Every 10 meters adds 1 atm pressure

Physics: Standard reference pressure for equations, thermodynamics.

  • Thermodynamics: Heat capacities typically defined at 1 atm
  • Boiling points: Water boils at 100°C only at 1 atm
  • Phase diagrams: Reference state for matter phase transitions

Engineering: High-pressure systems, pressure vessels, gas storage.

  • Vessel ratings: Designed for X psig over 1 atm ambient
  • Cylinder classifications: Based on working pressure as multiples of atm

Additional Unit Information

About Kilogram-force per Square Centimeter (kgf/cm²)

How do I convert kgf/cm² to bar?

Formula: bar = kgf/cm² × 0.980665

Quick approximation: 1 kgf/cm² ≈ 1 bar (2% difference)

Exact examples:

  • 1 kgf/cm² = 0.981 bar
  • 2 kgf/cm² = 1.961 bar
  • 5 kgf/cm² = 4.903 bar
  • 10 kgf/cm² = 9.807 bar
  • 100 kgf/cm² = 98.07 bar

Inverse: 1 bar = 1.0197 kgf/cm²

How do I convert kgf/cm² to PSI?

Formula: PSI = kgf/cm² × 14.2233

Examples:

  • 1 kgf/cm² = 14.22 PSI
  • 2 kgf/cm² = 28.45 PSI
  • 5 kgf/cm² = 71.12 PSI
  • 10 kgf/cm² = 142.23 PSI
  • 100 kgf/cm² = 1,422.33 PSI

Inverse: 1 PSI = 0.0703 kgf/cm²

How do I convert kgf/cm² to kPa or MPa?

Formula: kPa = kgf/cm² × 98.0665

Examples:

  • 1 kgf/cm² = 98.07 kPa = 0.0981 MPa
  • 5 kgf/cm² = 490.3 kPa = 0.490 MPa
  • 10 kgf/cm² = 980.7 kPa = 0.981 MPa
  • 50 kgf/cm² = 4,903 kPa = 4.90 MPa
  • 100 kgf/cm² = 9,807 kPa = 9.81 MPa

Quick rule: Multiply by ~100 to get kPa, divide by ~10 to get MPa

What is the difference between kgf/cm² and kg/cm²?

Same unit: kgf/cm² and kg/cm² refer to the same thing

kgf/cm² (kilogram-force per square centimeter):

  • Technically correct notation
  • "kgf" explicitly indicates force, not mass
  • Clearer in scientific context

kg/cm² (kilogram per square centimeter):

  • Shorthand notation
  • Technically incorrect (kg is mass, not force)
  • Commonly used in industry, understood to mean kgf/cm²

In practice: Both notations used interchangeably. Context makes meaning clear.

Why is this unit not used anymore?

SI adoption (1970s-1980s): Most countries transitioned to SI units Ambiguity: "kg" is mass unit, not force (causes confusion) Gravity dependence: kgf assumes standard gravity (9.80665 m/s²) Better alternatives: Bar, kPa, MPa clearer and SI-compliant

Modern replacements:

  • Bar: Easy conversion (1 kgf/cm² ≈ 1 bar)
  • kPa: SI standard for tire pressure
  • MPa: SI standard for high pressures, material strength

Still seen:

  • Older equipment specifications
  • Some Asian manufacturing (China, India, Japan)
  • Historical engineering documents
  • Legacy pressure gauges

Conversion tip: For quick estimates, treat 1 kgf/cm² as approximately 1 bar or 14 PSI.

About Atmosphere (atm)

How many PSI is 1 atmosphere?

1 atm = 14.696 PSI (often rounded to 14.7 PSI)

Examples:

  • 2 atm = 29.4 PSI (10m dive depth)
  • 3 atm = 44.1 PSI (20m dive depth)
  • 10 atm = 147 PSI (compressed air)
  • 100 atm = 1,470 PSI (gas cylinder)

How many atmospheres in a bar?

1 bar = 0.986923 atm (approximately 1 atm, ~1.3% difference)

Conversion:

  • 1 atm = 1.01325 bar
  • 10 atm = 10.1325 bar
  • 100 atm = 101.325 bar
  • 200 atm = 202.65 bar (scuba tank)

Why different?: Bar defined as exactly 100,000 Pa; atm defined as 101,325 Pa.

Atmosphere to Bar converter →

What pressure is 2 atmospheres?

2 atm = 202,650 Pa = 202.65 kPa = 29.4 PSI = 2.026 bar = 1,520 mmHg

Physical meaning:

  • Diving 10 meters (33 feet) underwater
  • Absolute pressure at 10m depth
  • Double the surface atmospheric pressure
  • Pressure inside a pressure cooker

How do I calculate diving depth pressure?

Formula: Total Pressure (atm) = 1 + (Depth in meters ÷ 10)

Or: Total Pressure (atm) = 1 + (Depth in feet ÷ 33)

Examples:

  • 10m (33ft): 1 + (10÷10) = 2 atm
  • 20m (66ft): 1 + (20÷10) = 3 atm
  • 30m (99ft): 1 + (30÷10) = 4 atm
  • 40m (131ft): 1 + (40÷10) = 5 atm

Note: Freshwater calculation uses 10.3m; saltwater 10m per atmosphere.

What is STP in chemistry?

STP (Standard Temperature and Pressure):

  • Pressure: 1 atm = 101,325 Pa = 100 kPa (IUPAC uses 100 kPa)
  • Temperature: 0°C = 273.15 K

Purpose: Reference conditions for gas law calculations

Molar volume at STP: 22.414 L/mol (IUPAC: 22.711 L/mol at 100 kPa)

SATP (Standard Ambient):

  • Pressure: 1 atm = 101,325 Pa
  • Temperature: 25°C = 298.15 K
  • Molar volume: 24.465 L/mol

More commonly used in modern chemistry.
