kilogram-force/square meter Unit Converter

Definition of kilogram-force/square meter unit

Kilogram-force per square meter (kgf/m²) is a pressure unit equal to the force exerted by one kilogram-force distributed over one square meter. It equals approximately 9.80665 pascals, because one kilogram-force is defined as 9.80665 newtons.

History of kilogram-force/square meter unit

The kilogram-force per square meter developed from gravitational-unit systems that measured force using the weight of a standard kilogram under Earth’s gravity. It was used alongside kilogram-force per square centimeter and technical atmospheric units in engineering and industrial practice, especially before SI adoption. In 1948, the General Conference on Weights and Measures established the pascal as the coherent SI pressure unit, and the 1960 SI framework reinforced its use. Consequently, kgf/m² is now largely historical or informal, with conversions based on standard gravity, 9.80665 m/s².

Applications of kilogram-force/square meter unit

Today, kilogram-force per square meter appears mainly in legacy engineering documents, older machinery specifications, soil and foundation studies, and some regional technical references. It may describe surface loading, material stress, or low pressure, although pascals are preferred internationally. For conversion, 1 kgf/m² equals 9.80665 Pa, while 1,000 kgf/m² equals approximately 9.80665 kPa.
