Formula
Kiloamperes = Milliamperes × 0.000001Direct answer
Multiply the entered milliamperes value by 0.000001 to express it in kiloamperes (kA). This converts milliampere (mA) to kiloampere (kA) within the documented electric current family.
Variables and formula
- Milliamperes (mA): the source value measured in milliampere.
- Kiloamperes (kA): the same quantity expressed in kiloampere.
- Conversion factor: 0.000001 kiloamperes per milliampere.
Kiloamperes = Milliamperes × 0.000001
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: 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.
Target 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.
The mA-to-kA 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.
- mA relationship: The decimal-prefix relationship is exact.
- kA relationship: The decimal-prefix relationship is exact.
To audit the factor through the family base unit, divide the raw dataset factors 0.001 by 1000. The generator emits that quotient once at 15 significant digits as the canonical direct factor 0.000001; runtime calculations do not divide the already-emitted base factors again.
Reproducible example
For 10 milliamperes, 10 × 0.000001 = 0.00001 kiloamperes. Repeating the same multiplication with the stated factor reproduces the displayed conversion before interface rounding.
Directional scale check
Because one milliampere contains 0.000001 kiloamperes, the target number is smaller 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 mA | 1 × 0.000001 |
0.000001 kA |
| 10 mA | 10 × 0.000001 |
0.00001 kA |
| 100 mA | 100 × 0.000001 |
0.0001 kA |
| 1000 mA | 1000 × 0.000001 |
0.001 kA |
Interpretation
Read the result as kiloamperes, not milliamperes. A value entered as mA leaves the calculator labelled kA; 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
- mA means milliampere; MA means megaampere.
- kA is current; kAh would be charge.
