How to convert coulombs per foot to coulombs per meter
Linear charge density describes a line distribution. Converting it to surface or volume charge density requires the geometry of that distribution.
Use x for the value in C/ft, b for the intermediate value in C/m, and y for the result in C/m.
C/m = C/ft × 3.280839895013123
Worked examples
10 C/ft ≈ 32.8083989501 C/m
Step 1: (10 × 3.28083989501) ≈ 32.8083989501 C/m.
Step 2: 32.8083989501 ÷ 1 ≈ 32.8083989501 C/m.20 C/ft ≈ 65.6167979003 C/m
Step 1: (20 × 3.28083989501) ≈ 65.6167979003 C/m.
Step 2: 65.6167979003 ÷ 1 ≈ 65.6167979003 C/m.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Coulombs per foot
Coulombs per foot (C/ft) measures linear charge density under the conventions above. The base value in C/m is (x × 3.28083989501), where x is the numerical value in C/ft. Factors shown here are rounded for display; calculations use the stored factor.
About Coulombs per meter
Coulombs per meter (C/m) measures linear charge density under the conventions above. The base value in C/m is (x × 1), where x is the numerical value in C/m. Factors shown here are rounded for display; calculations use the stored factor.
