What is a Kilogram-force per Square Meter and a Technical Atmosphere?

1 kgf/m² = 9.807 Pa = 0.009807 kPa = 0.09807 mbar = 0.001422 PSI = 0.0736 mmHg

Also written as: kg/m², kgf·m⁻², kilogram-force per square meter

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

Relationship to other kgf units:

  • 10,000 kgf/m² = 1 kgf/cm² (technical atmosphere)
  • 1 kgf/m² = 1 mm water column (approximately)

1 at = 1 kgf/cm² = 98,066.5 Pa = 98.07 kPa = 0.9807 bar = 0.968 atm = 14.223 PSI = 735.6 mmHg

Symbol: at (from German "technische Atmosphäre")

Also written as: kgf/cm², kg/cm², technical atmosphere, metric atmosphere (not standard atmosphere!)

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

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

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

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

Common Uses for kilograms-force per square meter

Obsolete: Rarely used in modern engineering. Historical Documents: May appear in pre-1980s European/Soviet technical literature. Confusion Source: Sometimes mistaken for Pascal in old documents.

When to Use technical atmospheres

Historical: European engineering (Germany, Austria, Switzerland) pre-1980s. Current: Some Asian countries (China, Russia, Japan) still use occasionally. Older Equipment: Pressure gauges, hydraulic systems from mid-1900s. Legacy Specs: Old engineering drawings, technical manuals.

Additional Unit Information

About Kilogram-force per Square Meter (kgf/m²)

How do I convert kgf/m² to Pa or kPa?

Formula: Pa = kgf/m² × 9.807

Examples:

  • 1 kgf/m² = 9.807 Pa ≈ 10 Pa
  • 10 kgf/m² = 98.07 Pa ≈ 0.1 kPa
  • 100 kgf/m² = 980.7 Pa ≈ 1 kPa
  • 1,000 kgf/m² = 9,807 Pa ≈ 10 kPa

Quick approximation: Multiply by 10 to get Pa (2% error)

kgf/m² to Pascal converter →

Is kgf/m² the same as Pascal?

No! But numerically close (common source of confusion)

kgf/m² (kilogram-force per square meter):

  • 1 kgf/m² = 9.807 Pa
  • Gravitational unit (depends on Earth's gravity)
  • Obsolete, not SI-compliant

Pa (Pascal = Newton per square meter):

  • 1 Pa = 1 N/m²
  • SI unit (independent of gravity)
  • Modern standard

Why confusion?:

  • Values similar in magnitude (differ by factor ~10)
  • Old documents sometimes mislabeled Pa as "kg/m²"
  • Both measure pressure

To clarify: If document says "kg/m²", determine if it means:

  • kgf/m² (multiply by 9.807 to get Pa)
  • Pa (mislabeled, use value directly)

How does kgf/m² relate to kgf/cm²?

1 kgf/cm² = 10,000 kgf/m² (factor of 10,000)

kgf/cm² (technical atmosphere):

  • High pressures (hydraulics, materials)
  • 1 kgf/cm² = 98,066.5 Pa ≈ 1 bar
  • Still used in some Asian countries

kgf/m²:

  • Very low pressures
  • 1 kgf/m² = 9.807 Pa
  • Almost completely obsolete

Conversion:

  • 1 kgf/cm² = 10,000 kgf/m²
  • (100 cm)² = 10,000 cm² per m²

Why is this unit not used anymore?

SI adoption (1970s-1980s): Countries switched to SI units (Pa, kPa, MPa)

Problems with kgf units:

  • Ambiguity: "kg" is mass, not force (requires "kgf" clarification)
  • Gravity dependence: Assumes standard gravity (9.80665 m/s²)
  • Confusion: Easy to mistake for Pascal or mass-per-area
  • Obsolete: No modern instruments calibrated in kgf/m²

Modern replacement: Pascal (Pa) and multiples

  • 1 kgf/m² → 10 Pa (approximately)
  • 100 kgf/m² → 1 kPa
  • 1,000 kgf/m² → 10 kPa

Where still seen:

  • Very old technical manuals (pre-1980s)
  • Historical scientific papers
  • Soviet/Russian legacy documents

Should I convert old kgf/m² values?

Yes, for modern use convert to Pa or kPa

Conversion steps:

  1. Identify if unit truly kgf/m² (check context, date)
  2. Multiply by 9.807 to get Pascals
  3. Convert to appropriate modern unit (Pa, kPa, mbar)

Example:

  • Old spec: "Building pressure 5 kgf/m²"
  • Convert: 5 × 9.807 = 49 Pa ≈ 0.5 mbar
  • Modern: "Building pressure 50 Pa" or "0.5 mbar"

Watch for mislabeling: Some old documents used "kg/m²" when they meant Pa—double-check with other values in document to confirm.

About Technical Atmosphere (at)

What is the difference between "at" and "atm"?

Different units! (Common source of confusion)

at (technical atmosphere):

  • 1 at = 1 kgf/cm² = 98,066.5 Pa
  • Engineering unit based on kilogram-force
  • Symbol: at
  • Historical European engineering

atm (standard atmosphere):

  • 1 atm = 101,325 Pa (exactly, by definition)
  • Based on sea-level atmospheric pressure
  • Symbol: atm
  • Scientific/meteorological standard

Relationship: 1 atm = 1.033 at (about 3% higher)

Why confusion?: Names sound similar, values close (both ≈ atmospheric pressure)

How do I convert at to bar?

Formula: bar = at × 0.980665

Quick approximation: 1 at ≈ 1 bar (1.9% difference)

Exact conversions:

  • 1 at = 0.981 bar
  • 2 at = 1.961 bar
  • 5 at = 4.903 bar
  • 10 at = 9.807 bar
  • 100 at = 98.07 bar

Inverse: 1 bar = 1.0197 at

Why so close?: Bar defined (originally) to be close to atmospheric pressure, similar motivation as technical atmosphere

How do I convert at to PSI?

Formula: PSI = at × 14.2233

Examples:

  • 1 at = 14.22 PSI
  • 2 at = 28.45 PSI
  • 5 at = 71.12 PSI (typical air compressor)
  • 10 at = 142.23 PSI
  • 100 at = 1,422.33 PSI (high pressure)

Inverse: 1 PSI = 0.0703 at

Memory aid: 1 at ≈ 14 PSI

at to PSI converter →

How do I convert at to kPa or MPa?

Formula: kPa = at × 98.0665

Examples:

  • 1 at = 98.07 kPa ≈ 0.1 MPa
  • 5 at = 490.3 kPa ≈ 0.5 MPa
  • 10 at = 980.7 kPa ≈ 1 MPa
  • 50 at = 4,903 kPa ≈ 5 MPa
  • 100 at = 9,807 kPa ≈ 10 MPa

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

Why is this unit not used anymore?

SI adoption (1970s-1980s): Most countries transitioned to SI units (Pa, kPa, MPa, bar)

Problems with technical atmosphere:

  • Not SI-compliant: Based on kilogram-force (gravitational unit)
  • Ambiguity: "kg" is mass, not force (kgf needed for clarity)
  • Gravity dependence: Assumes standard gravity (9.80665 m/s²)
  • Confusion: Easy to confuse with standard atmosphere (atm)

Modern replacements:

  • Bar: 1 at ≈ 1 bar (easy conversion)
  • kPa: 1 at ≈ 100 kPa
  • MPa: For high pressures (1 at = 0.1 MPa)

Still seen in:

  • Older European equipment specifications
  • Chinese industrial standards (some applications)
  • Russian/former Soviet engineering documents
  • Japanese industrial equipment (occasionally)
  • Legacy pressure gauges and instruments

For new designs: Use bar, kPa, or MPa instead of at

Historical importance: Was convenient unit when bar not yet standardized, and provided easy mental approximation to atmospheric pressure.
