inH2O to kgf/cm² Converter
Pressure · unit-converter
Convert inH2O 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 inH2O
Inches of water column (inH2O) is common in low-pressure HVAC and duct static-pressure measurements.
About kgf/cm²
Kilogram-force per square centimeter (kgf/cm²) is common in pump/compressor and older industrial gauge specifications.
How to convert inch of water (inh2o, 4 °c) to kilogram-force per square centimeter
1 inh2o equals 0.00254 kgf/cm² in this tool (via pascal):
1 inh2o = (249.08891 Pa ÷ 98066.5 Pa) kgf_cm2 = 0.00254 kgf_cm2
Each inh2o carries 249.08891 Pa and each kgf/cm² 98066.5 Pa, so one inh2o equals 249.08891 ÷ 98066.5 kgf_cm2.
Let p(inh2o) be pressure in inH2O (inh2o), and p(kgf_cm2) in kgf/cm² (kgf_cm2). Then:
p(kgf_cm2) = p(inh2o) × (249.08891 / 98066.5)
Equivalently, divide by how many inh2o fit into one kgf_cm2 (Pa per kgf_cm2 divided by Pa per inh2o):
p(kgf_cm2) = p(inh2o) ÷ 393.7007874015748
Examples
Example #1: Convert 1 inh2o to kgf/cm²
1 inh2o = 1 inh2o × (249.08891/98066.5) kgf_cm2 = 0.00254 kgf_cm2
1 inh2o = 1 inh2o ÷ 393.7007874015748 = 0.00254 kgf_cm2
1 inh2o × (249.08891/98,066.5) = 0.002540 kgf_cm2
Example #2: Convert 10 inh2o to kgf/cm²
10 inh2o = 10 inh2o × (249.08891/98066.5) kgf_cm2 = 0.0254 kgf_cm2
10 inh2o = 10 inh2o ÷ 393.7007874015748 = 0.0254 kgf_cm2
10 inh2o × (249.08891/98,066.5) = 0.025400 kgf_cm2
Summary
To convert inH2O to kgf/cm², multiply the value in inh2o by (249.08891 Pa per inh2o) / (98066.5 Pa per kgf_cm2). Equivalently: value_kgf_cm2 = value_inh2o × (249.08891 / 98066.5). Numerically, 1 inh2o equals 0.00254 kgf_cm2.
Relationship context
Both inH2O and kgf/cm² are converted by fixed multiples of the pascal. Multiplying by (Pa per inh2o) ÷ (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.
