2References & settings

Sensor leakage currentOften in the pA to nA range; best viewed in picoamps or nanoamps.

Low-power standbyMany low-power circuits are described in μA, making battery life easier to estimate.

Indicator LEDTypical operating current is about 5 mA to 20 mA; calculate with the current-limiting resistor.

USB chargingTypical current is about 0.5 A to 3 A; device protocols affect the actual value.

Home circuitCommon breaker currents are 5 A to 16 A; choose based on codes and wire size.

Industrial busbarMay reach hundreds of amps to kiloamps; judge with temperature rise and protection design.

Conversion relations	Notes
1 A = 1000 mA = 1000000 μA	The ampere is the SI base unit of electric current.
1 mA = 0.001 A	Milliamps are common in small electronics and LED circuits.
1 μA = 0.000001 A	Microamps are common in low-power and precision measurement scenarios.
1 nA = 0.000000001 A	Nanoamps and picoamps suit sensors, leakage current, and weak signals.
1 kA = 1000 A	Kiloamps are common in power, busbar, and short-circuit current estimates.

Instructions

Software Usage Instructions

Set the current parameter: Enter the current value to be converted in “Input value”. Decimals and scientific notation are supported, such as 20, 0.02, and 1e-6.
Select the source unit: Choose ampere (A), milliampere (mA), microampere (μA), nanoampere (nA), picoampere (pA), femtoampere (fA), kiloampere (kA), megaampere (MA), or gigaampere (GA) based on the original data.
Select the key target unit: Choose the target unit you want to focus on. The tool will display both the highlighted result and all unit conversion results at the same time.
Adjust display parameters: You can set standard decimal, scientific notation, engineering notation, decimal places, thousands separators, and copy format for easy use in spreadsheets, reports, or engineering records.
Use sample data: Click examples such as sensor leakage current, low-power standby, indicator LED, USB charging, and industrial busbar to quickly load data for common scenarios.
Copy or export results: You can click an individual result to copy it, or copy all results; if you need tabular organization, you can export a CSV file.
Batch conversion: Switch to “Batch & Reference” and enter one data item per line, such as 20 mA, 0.5 A, or 1500 μA. After clicking “Batch Convert”, you can copy or export the results.
Save settings: Click “Save Settings” to keep frequently used units, target units, display format, and precision settings for convenient use next time.

FAQ

A: It supports femtoampere (fA), picoampere (pA), nanoampere (nA), microampere (μA), milliampere (mA), ampere (A), kiloampere (kA), megaampere (MA), and gigaampere (GA), covering weak currents, common electronic currents, and high-current scenarios.

A: Using ampere (A) as the base unit, 1A = 1000mA = 1000000μA; 1mA = 0.001A; 1μA = 0.000001A. The tool automatically performs the conversion based on the selected unit.

A: Scientific notation is suitable for displaying very large or very small values, such as 2e-6; in engineering notation, the exponent changes in multiples of 3, making it closer to engineering unit expressions such as mA, μA, and kA.

A: Enter one item per line. The recommended format is “value unit”, such as 20 mA, 0.5 A, or 1500 μA. If no unit is entered, it will be processed according to the currently set default source unit.

A: They can be used for circuit design, organizing component parameters, low-power estimation, sensor leakage current conversion, and learning calculations. For actual engineering component selection, voltage, power, temperature rise, wire diameter, and protection device parameters should also be considered.

A: When values are very large or very small, e format is easier to read. For example, 1e-6 means 0.000001. You can also switch the display format to regular decimal, scientific notation, or engineering notation.
