About Kilopound per Square Inch (ksi)
An imperial unit of pressure equal to exactly 1,000 psi (≈ 6.895 MPa). KSI is the standard US unit for reporting material strength: structural-steel yield (A36 = 36 ksi, A992 W-shapes = 50 ksi, A572-Gr50 plate = 50 ksi, A514 quenched-tempered = 100 ksi), bolt-grade tensile strength (SAE Grade 5 = 120 ksi, Grade 8 = 150 ksi, ASTM A325 = 105-120 ksi, A490 = 150 ksi), aluminum aerospace alloys (7075-T6 ultimate = ~83 ksi), and the S-N fatigue curves in MMPDS / ASME Section VIII Division 3. US structural codes (AISC Steel Construction Manual, AASHTO LRFD Bridge Design), aerospace stress reports, and oil-and-gas casing specifications (API 5CT) all express allowables and yield in ksi. When cross-referencing US alloys against international material databases (typically MPa), the conversion ksi × 6.895 → MPa is essentially universal.
About Kilopascal (kPa)
A metric unit of pressure equal to exactly 1,000 pascals (1 kPa = 1,000 N/m²). Kilopascals are the everyday SI pressure unit outside the US: passenger car tire pressure in Europe and Australia is specified in kPa (typically 220-250 kPa cold), building HVAC duct static pressure is in kPa, and the ISO 5198 / IEC 60534 valve standards quote rated pressures in kPa. Weather forecasters quote surface atmospheric pressure in hectopascals (1 kPa = 10 hPa); a typical sea-level barometric reading is 1013 hPa = 101.3 kPa. The kPa is the standard report unit in clinical respiratory physiology (PaCO₂, PaO₂ in some ICUs) and in scientific gauge pressure measurement. Common conversions: kPa to psi is divide by 6.895; kPa to bar is divide by 100; kPa to mmHg is multiply by 7.5006.

Understanding Kilopounds per Square Inch
The Kilopound per Square Inch (symbol: ksi) is a unit of pressure. An imperial unit of pressure equal to exactly 1,000 psi (≈ 6.895 MPa). KSI is the standard US unit for reporting material strength: structural-steel yield (A36 = 36 ksi, A992 W-shapes = 50 ksi, A572-Gr50 plate = 50 ksi, A514 quenched-tempered = 100 ksi), bolt-grade tensile strength (SAE Grade 5 = 120 ksi, Grade 8 = 150 ksi, ASTM A325 = 105-120 ksi, A490 = 150 ksi), aluminum aerospace alloys (7075-T6 ultimate = ~83 ksi), and the S-N fatigue curves in MMPDS / ASME Section VIII Division 3. US structural codes (AISC Steel Construction Manual, AASHTO LRFD Bridge Design), aerospace stress reports, and oil-and-gas casing specifications (API 5CT) all express allowables and yield in ksi. When cross-referencing US alloys against international material databases (typically MPa), the conversion ksi × 6.895 → MPa is essentially universal.
It belongs to the imperial measurement system.
Kilopounds per Square Inch are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
Understanding Kilopascals
The Kilopascal (symbol: kPa) is a unit of pressure. A metric unit of pressure equal to exactly 1,000 pascals (1 kPa = 1,000 N/m²). Kilopascals are the everyday SI pressure unit outside the US: passenger car tire pressure in Europe and Australia is specified in kPa (typically 220-250 kPa cold), building HVAC duct static pressure is in kPa, and the ISO 5198 / IEC 60534 valve standards quote rated pressures in kPa. Weather forecasters quote surface atmospheric pressure in hectopascals (1 kPa = 10 hPa); a typical sea-level barometric reading is 1013 hPa = 101.3 kPa. The kPa is the standard report unit in clinical respiratory physiology (PaCO₂, PaO₂ in some ICUs) and in scientific gauge pressure measurement. Common conversions: kPa to psi is divide by 6.895; kPa to bar is divide by 100; kPa to mmHg is multiply by 7.5006.
