Formula
Milliamperes = Kiloamperes × 1000000Direct answer
Multiply the entered kiloamperes value by 1000000 to express it in milliamperes (mA). This converts kiloampere (kA) to milliampere (mA) within the documented electric current family.
Variables and formula
- Kiloamperes (kA): the source value measured in kiloampere.
- Milliamperes (mA): the same quantity expressed in milliampere.
- Conversion factor: 1000000 milliamperes per kiloampere.
Milliamperes = Kiloamperes × 1000000
The generator emits numeric factors with at most 15 significant digits. Calculator results keep up to 10 significant digits for display; this formatting does not increase the precision of the measurement.
Unit definitions and named variants
Source unit: kiloampere (kA). A kiloampere is the SI decimal multiple formed by applying kilo (10^3) to ampere: 1 kA = 1000 A. The canonical kiloampere definition is used; no alternate named variant is implied. Reference: Bureau International des Poids et Mesures: The International System of Units (SI), 9th edition, version 4.01.
Target unit: milliampere (mA). A milliampere is the SI decimal submultiple formed by applying milli (10^-3) to ampere: 1 mA = 0.001 A. The canonical milliampere definition is used; no alternate named variant is implied. Reference: Bureau International des Poids et Mesures: The International System of Units (SI), 9th edition, version 4.01.
The kA-to-mA direction remains inside the electric current quantity; it changes the unit label and numerical scale, not the kind of quantity being measured.
Relationship and precision
The named unit relationships are defined or exact, so the conversion is exact before display rounding and source-measurement uncertainty.
- kA relationship: The decimal-prefix relationship is exact.
- mA relationship: The decimal-prefix relationship is exact.
To audit the factor through the family base unit, divide the raw dataset factors 1000 by 0.001. The generator emits that quotient once at 15 significant digits as the canonical direct factor 1000000; runtime calculations do not divide the already-emitted base factors again.
Reproducible example
For 10 kiloamperes, 10 × 1000000 = 10000000 milliamperes. Repeating the same multiplication with the stated factor reproduces the displayed conversion before interface rounding.
Directional scale check
Because one kiloampere contains 1000000 milliamperes, the target number is larger than the source number for every positive input. Zero maps to zero, while negative inputs are preserved as signed values under the stated direction convention.
| Source amount | Calculation | Target amount |
|---|---|---|
| 1 kA | 1 × 1000000 |
1000000 mA |
| 10 kA | 10 × 1000000 |
10000000 mA |
| 100 kA | 100 × 1000000 |
100000000 mA |
| 1000 kA | 1000 × 1000000 |
1000000000 mA |
Interpretation
Read the result as milliamperes, not kiloamperes. A value entered as kA leaves the calculator labelled mA; this directional distinction matters even when the two units describe the same electric current quantity.
Assumptions and limitations
- A negative value denotes current opposite the chosen positive reference direction.
- Charge transferred over time and current density require additional quantities and are outside this family.
- A conversion does not add significant figures to the source measurement.
Common mistakes
- The symbol is kA with lowercase k.
- mAh is charge capacity, not current.
