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

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 Torr = 1/760 atm (exactly) = 133.322 Pa = 1.333 mbar ≈ 1 mmHg (0.000015% difference)

Key relationships:

  • 760 Torr = 1 atmosphere (exactly)
  • 1 Torr ≈ 1 mmHg (virtually identical)
  • 1 mTorr = 0.001 Torr (millitorr)

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 Torr belongs to the imperial/US customary system.

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

Explore the typical applications for both Kilogram-force per Square Centimeter (imperial/US) and Torr (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 torr

Vacuum Technology: High vacuum pumps, vacuum chambers, thin-film deposition. Physics Laboratories: Pressure measurement in evacuated systems. Chemistry: Vapor pressure measurements, distillation processes. Medicine: Blood pressure (often interchangeable with mmHg).

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 Torr (Torr)

What is the difference between Torr and mmHg?

Almost identical: 1 Torr ≈ 1 mmHg (difference < 0.000015%)

Torr: Defined as exactly 1/760 atmosphere (by definition) mmHg: Based on mercury density at 0°C and standard gravity

Practical usage:

  • Vacuum technology: Prefers Torr (more precise definition)
  • Medicine: Prefers mmHg (traditional, familiar)
  • Chemistry: Uses both interchangeably

Conversion: For all practical purposes, treat them as equal.

How many torr in 1 atmosphere?

1 atm = 760 Torr (exactly, by definition)

Examples:

  • 2 atm = 1,520 Torr
  • 0.5 atm = 380 Torr
  • 0.001 atm = 0.76 Torr
  • 10⁻⁶ atm = 0.00076 Torr = 0.76 mTorr (millitorr)

How do I convert Torr to PSI?

Formula: PSI = Torr × 0.0193368

Examples:

  • 760 Torr = 14.7 PSI (1 atmosphere)
  • 120 Torr = 2.32 PSI (systolic blood pressure)
  • 80 Torr = 1.55 PSI (diastolic blood pressure)
  • 1 Torr = 0.0193 PSI
  • 0.001 Torr = 0.0000193 PSI

How do I convert Torr to Pascals?

Formula: Pa = Torr × 133.322

Examples:

  • 1 Torr = 133.322 Pa = 0.133 kPa
  • 760 Torr = 101,325 Pa = 101.325 kPa (1 atm)
  • 0.001 Torr (1 mTorr) = 0.133 Pa
  • 10⁻⁶ Torr = 0.000133 Pa

Why use Torr instead of mmHg in vacuum technology?

Torr advantages:

  • Exact definition: 1/760 atm (no ambiguity)
  • Independent: Not dependent on mercury properties
  • Standard: Agreed upon by vacuum scientists
  • Precision: Better defined for scientific work

mmHg issues:

  • Temperature dependent: Mercury density varies
  • Gravity dependent: Varies slightly with location
  • Less precise: For ultra-high vacuum measurements

In practice: Both work fine for most applications, but Torr is preferred in vacuum physics and engineering.
