mmH2O to kgf/cm² Converter
Pressure · unit-converter
Convert mmH2O to kgf/cm² with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).
About mmH2O
Millimeters of water column (mmH2O) is used for very low differential pressure in instrumentation and ventilation.
About kgf/cm²
Kilogram-force per square centimeter (kgf/cm²) is common in pump/compressor and older industrial gauge specifications.
How to convert millimeter of water (mmh2o, 4 °c) to kilogram-force per square centimeter
1 mmh2o equals 0.00009999999999999999 kgf/cm² in this tool (via pascal):
1 mmh2o = (9.80665 Pa ÷ 98066.5 Pa) kgf_cm2 = 0.00009999999999999999 kgf_cm2
Each mmh2o carries 9.80665 Pa and each kgf/cm² 98066.5 Pa, so one mmh2o equals 9.80665 ÷ 98066.5 kgf_cm2.
Let p(mmh2o) be pressure in mmH2O (mmh2o), and p(kgf_cm2) in kgf/cm² (kgf_cm2). Then:
p(kgf_cm2) = p(mmh2o) × (9.80665 / 98066.5)
Equivalently, divide by how many mmh2o fit into one kgf_cm2 (Pa per kgf_cm2 divided by Pa per mmh2o):
p(kgf_cm2) = p(mmh2o) ÷ 10000
Examples
Example #1: Convert 1 mmh2o to kgf/cm²
1 mmh2o = 1 mmh2o × (9.80665/98066.5) kgf_cm2 = 0.0001 kgf_cm2
1 mmh2o = 1 mmh2o ÷ 10000 = 0.0001 kgf_cm2
1 mmh2o × (9.80665/98,066.5) = 0.000100 kgf_cm2
Example #2: Convert 10 mmh2o to kgf/cm²
10 mmh2o = 10 mmh2o × (9.80665/98066.5) kgf_cm2 = 0.001 kgf_cm2
10 mmh2o = 10 mmh2o ÷ 10000 = 0.001 kgf_cm2
10 mmh2o × (9.80665/98,066.5) = 0.001000 kgf_cm2
Summary
To convert mmH2O to kgf/cm², multiply the value in mmh2o by (9.80665 Pa per mmh2o) / (98066.5 Pa per kgf_cm2). Equivalently: value_kgf_cm2 = value_mmh2o × (9.80665 / 98066.5). Numerically, 1 mmh2o equals 0.00009999999999999999 kgf_cm2.
Relationship context
Both mmH2O and kgf/cm² are converted by fixed multiples of the pascal. Multiplying by (Pa per mmh2o) ÷ (Pa per kgf_cm2) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
