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

1 ksi = 1,000 PSI = 6.895 MPa = 68.95 bar = 6,895 kPa = 47.88 atm

ksi = kilo-pound per square inch = 1,000 pounds-force per square inch

Also written as: KSI, 1000 PSI, 1 KPSI

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 Kilopound per Square Inch belongs to the imperial/US customary system.

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 Kilopound per Square Inch (ksi)

How do I convert ksi to MPa?

Formula: MPa = ksi × 6.895

Examples:

  • 36 ksi = 248 MPa (A36 steel)
  • 50 ksi = 345 MPa (A992 steel)
  • 60 ksi = 414 MPa (rebar)
  • 100 ksi = 689 MPa (high-strength)
  • 1 ksi = 6.895 MPa

ksi to MPa converter →

What does "36 ksi steel" mean?

36 ksi = yield strength of structural steel

A36 Steel (most common structural):

  • Yield strength: 36,000 PSI = 36 ksi = 248 MPa
  • Tensile strength: 58-80 ksi (ultimate strength before breaking)
  • Applications: Beams, columns, general construction

Yield strength: Stress at which permanent deformation begins Tensile strength: Maximum stress before failure

Common grades:

  • A36: 36 ksi (older standard, still common)
  • A572 Grade 50: 50 ksi (modern standard)
  • A992: 50 ksi yield (I-beams, wide flanges)

How do I convert ksi to PSI?

Formula: PSI = ksi × 1,000

Examples:

  • 1 ksi = 1,000 PSI
  • 36 ksi = 36,000 PSI (A36 steel)
  • 50 ksi = 50,000 PSI (A992 steel)
  • 4 ksi = 4,000 PSI (concrete)
  • 0.1 ksi = 100 PSI

Why use ksi?: Simpler than writing "36,000 PSI"—say "36 ksi" instead

What is typical concrete strength in ksi?

Residential/Light commercial:

  • Sidewalks, patios: 3 ksi (3,000 PSI)
  • Garage floors, driveways: 3.5-4 ksi
  • Foundation slabs: 3-4 ksi

Commercial:

  • Commercial floors: 4-5 ksi
  • Parking structures: 4-5 ksi
  • Warehouse slabs: 5-6 ksi

Structural:

  • Columns, beams: 5-8 ksi
  • High-rise buildings: 8-14 ksi
  • Bridge elements: 4-6 ksi

Special:

  • Precast prestressed: 5-10 ksi
  • Ultra-high performance: 20-30 ksi

Note: Concrete strength measured at 28 days after pouring

Why does US use ksi instead of MPa?

Historical: US construction industry established with imperial units Standards: AISC, ACI, ASTM all specify ksi Training: US engineers educated with ksi Continuity: Existing specs, calculations, tables in ksi Conversion: 1 ksi ≈ 7 MPa (approximate, easy mental math)

Rest of world: Uses MPa (SI standard)

  • 36 ksi = 248 MPa (A36 steel equivalent)
  • 50 ksi = 345 MPa (common grade)

Dual labeling: International projects often show both units
