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 Torr (torr)
A unit of pressure defined as exactly 1/760 of a standard atmosphere (≈ 133.322 Pa). Named after 17th-century physicist Evangelista Torricelli, who in 1643 invented the mercury barometer while studying why suction-lift pumps fail above ~10 m — establishing that the atmosphere itself has weight. The torr is the primary unit in modern vacuum technology and semiconductor fabrication: a "rough vacuum" is ~1 torr, "medium vacuum" 10⁻³ torr (typical of mechanical-pump-only systems), "high vacuum" 10⁻⁶ torr (achievable with turbomolecular pumps, used in mass spectrometry and electron microscopy), and "ultrahigh vacuum" (UHV) 10⁻⁹ torr or lower (semiconductor MBE, surface science, particle accelerators). Manufacturing fabs quote chamber pressures in torr or mTorr (10⁻³ torr) at every process step. Numerically the torr is almost identical to the mmHg (1 torr ≈ 1.000000 mmHg under modern definitions; historically they differed by 0.000015%).

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 Torr
The Torr (symbol: torr) is a unit of pressure. A unit of pressure defined as exactly 1/760 of a standard atmosphere (≈ 133.322 Pa). Named after 17th-century physicist Evangelista Torricelli, who in 1643 invented the mercury barometer while studying why suction-lift pumps fail above ~10 m — establishing that the atmosphere itself has weight. The torr is the primary unit in modern vacuum technology and semiconductor fabrication: a "rough vacuum" is ~1 torr, "medium vacuum" 10⁻³ torr (typical of mechanical-pump-only systems), "high vacuum" 10⁻⁶ torr (achievable with turbomolecular pumps, used in mass spectrometry and electron microscopy), and "ultrahigh vacuum" (UHV) 10⁻⁹ torr or lower (semiconductor MBE, surface science, particle accelerators). Manufacturing fabs quote chamber pressures in torr or mTorr (10⁻³ torr) at every process step. Numerically the torr is almost identical to the mmHg (1 torr ≈ 1.000000 mmHg under modern definitions; historically they differed by 0.000015%).
Torr are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
