kgf/cm² to inH2O Converter
Pressure · unit-converter
Convert kgf/cm² to inH2O 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 kgf/cm²
Kilogram-force per square centimeter (kgf/cm²) is common in pump/compressor and older industrial gauge specifications.
About inH2O
Inches of water column (inH2O) is common in low-pressure HVAC and duct static-pressure measurements.
How to convert kilogram-force per square centimeter to inch of water (inh2o, 4 °c)
1 kgf/cm² equals 393.7007874015748 inh2o in this tool (via pascal):
1 kgf_cm2 = (98066.5 Pa ÷ 249.08891 Pa) inh2o = 393.7007874015748 inh2o
Each kgf/cm² carries 98066.5 Pa and each inh2o 249.08891 Pa, so one kgf_cm2 equals 98066.5 ÷ 249.08891 inh2o.
Let p(kgf_cm2) be pressure in kgf/cm² (kgf_cm2), and p(inh2o) in inH2O (inh2o). Then:
p(inh2o) = p(kgf_cm2) × (98066.5 / 249.08891)
Equivalently, divide by how many kgf_cm2 fit into one inh2o (Pa per inh2o divided by Pa per kgf_cm2):
p(inh2o) = p(kgf_cm2) ÷ 0.00254
Examples
Example #1: Convert 1 kgf_cm2 to inh2o
1 kgf_cm2 = 1 kgf_cm2 × (98066.5/249.08891) inh2o = 393.700787402 inh2o
1 kgf_cm2 = 1 kgf_cm2 ÷ 0.00254 = 393.700787402 inh2o
1 kgf_cm2 × (98,066.5/249.08891) = 393.700787 inh2o
Example #2: Convert 10 kgf_cm2 to inh2o
10 kgf_cm2 = 10 kgf_cm2 × (98066.5/249.08891) inh2o = 3937.00787402 inh2o
10 kgf_cm2 = 10 kgf_cm2 ÷ 0.00254 = 3937.00787402 inh2o
10 kgf_cm2 × (98,066.5/249.08891) = 3,937.007874 inh2o
Summary
To convert kgf/cm² to inH2O, multiply the value in kgf_cm2 by (98066.5 Pa per kgf_cm2) / (249.08891 Pa per inh2o). Equivalently: value_inh2o = value_kgf_cm2 × (98066.5 / 249.08891). Numerically, 1 kgf_cm2 equals 393.7007874015748 inh2o.
Relationship context
Both kgf/cm² and inH2O are converted by fixed multiples of the pascal. Multiplying by (Pa per kgf_cm2) ÷ (Pa per inh2o) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
