In the industrial pneumatic system, air compressor selection and equipment nameplate identification, the expression “0.6kg” is often seen, such as “working pressure: 0.6kg ‘. However, it needs to be clear:‘Kilometer’ itself is not a pressure unit., this is actually a shorthand for engineering habits, meaning0.6kg force per square centimeter (kgf/cm²), approximately equal0.059 MPa or 59 kPa.
Why use ‘kilograms ‘to describe the pressure?
Popular expression in the context of traditional engineering: 1 kgf/cm² ≈ 98.07 kPa, close to 0. 1 MPa to facilitate estimation. Therefore, ‘0.6kg ‘means 0.6 kgf/cm² ≈ 58.8 kPa, common in small pneumatic tools, packaging equipment and low pressure purging scenarios.
Unit conversion reference
- 0.6 kgf/cm² = 0.0588 MPa
- 0.6 kgf/cm² ≈ 58.8 kPa
- 0.6 kgf/cm² ≈ 8.5 psi (Pounds per square inch)
- 0.6 kgf/cm² ≈ 0.58 bar
note: Pascals are recommended in international standards (Pa) and its multiple (kPa, MPa), design documents and safety specifications should avoid using non-legal units such as ‘kilometer’ to prevent ambiguity or compliance risks.
