What this calculator does

Converts a measurement given in milliampere hours into coulombs using the defined conversion factor.

What your result means

The same quantity expressed in C instead of mAh. Nothing about the measurement itself changes.

Formula and working

C = mAh × 3.6

  1. 1

    Start with your value

    10 mAh

  2. 2

    Convert to coulomb

    10 × 3.6 = 36 C

  3. 3

    Convert into coulombs

    36 ÷ 1 = 36 C

  4. 4

    Result

    10 mAh = 36 C

Frequently asked questions

Symbols and assumptions

mAh
Input unit — milliampere hour
C
Output unit — coulomb
  • • Both units measure electric charge and battery capacity, so the physical quantity is unchanged by the conversion.
  • • The relationship is exactly linear: 1 mAh = 3.6 C.
  • • Values are converted through the SI base unit for this quantity rather than pair by pair.

  • • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
  • • Displayed figures are rounded for readability; the full stored precision of the C value is used in every onward calculation.
