Convert kgf/cm² to atm
Convert Technical Atmosphere (kgf/cm²) to Standard Atmosphere (atm). High precision tool for engineering legacy systems.

Precision: 6 decimal places
About
In older engineering documentation, particularly in Europe and Russia, pressure was often denoted in the "Technical Atmosphere" (at or kgf/cm²). This is distinct from the "Standard Atmosphere" (atm) used in modern thermodynamics and meteorology. The difference is subtle - approx 3% - but critical in high-pressure environments like hydraulics or boilers. This tool converts these legacy units to the standard atmosphere with 6-decimal precision.

Formulas
The conversion relies on the definition of standard gravity gn and the standard atmosphere pressure.
1 kgf/cm2 = 0.9678411053541 atm
Logic: Multiply the input value by this factor.

Frequently Asked Questions
"at" refers to the Technical Atmosphere (1 kgf/cm²), while "atm" is the Standard Atmosphere (101325 Pa). They are not interchangeable.
No, but they are very close. 1 kgf/cm² is roughly 0.98 bar. They are often treated as equal in rough estimates, but not in precision engineering.
It is still common in older hydraulic gauges, tire pressure specifications in some regions, and legacy piping schematics.
