Surface Charge Density Converter

Convert surface charge density between coulomb per square meter, coulomb per square centimeter, microcoulomb per square meter and more.

What this tool does

Convert surface charge density between coulomb per square meter, coulomb per square centimeter, microcoulomb per square meter and more. Type an amount in coulombs per square meter, choose the units, and the tool converts it to microcoulombs per square meter. It offers 9 surface charge density units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 9 options, including Coulomb per square meter, Millicoulomb per square meter, Microcoulomb per square meter, Nanocoulomb per square meter, Picocoulomb per square meter, Coulomb per square centimeter. Starts as Coulomb per square meter.
  • To: Choose one of the same 9 units as "From". Starts as Microcoulomb per square meter.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from coulombs per square meter to microcoulombs per square meter:

  • 1 C/m² = 1,000,000 µC/m²
  • 5 C/m² = 5,000,000 µC/m²
  • 10 C/m² = 10,000,000 µC/m²
  • 50 C/m² = 50,000,000 µC/m²
  • 100 C/m² = 100,000,000 µC/m²

Multiply the number of coulombs per square meter by 1,000,000 to get microcoulombs per square meter. Both units are exact definitions, so 1,000,000 is the exact factor: 1 C/m² = 1,000,000 µC/m².

Limitations

  • Converts the unit of a charge per area only. It does not work out electric fields or total charge.
