Current Converter

Convert between different units of electric current measurement including amperes, milliamperes, abamperes, statamperes, and more. Essential for electrical engineering and electronics applications.

Common Current Conversions

SI Prefixes:
• 1 kA = 1,000 A
• 1 mA = 0.001 A
• 1 μA = 0.000001 A
• 1 nA = 10⁻⁹ A
Electronics:
• LED: 10-30 mA typical
• Microcontroller: μA to mA
• USB: 100-500 mA standard
• Phone charger: 1-3 A
Power Systems:
• Household: 15-20 A circuits
• Industrial motors: 10-100 A
• Power lines: kA range
• Lightning: ~30 kA peak
Special Units:
• 1 abA = 10 A (CGS EMU)
• 1 Bi = 10 A (Biot)
• 1 A = 1 C/s
• 1 statA ≈ 3.34 × 10⁻¹⁰ A

⚡ Current Types & Definitions

DC Current: Constant magnitude and direction

AC Current: Alternating magnitude and direction

RMS Current: Root Mean Square, effective AC value

Peak Current: Maximum instantaneous current

Average Current: Mean current over time period

Definition: 1 Ampere = 1 Coulomb per second (C/s)

⚠️ Current Safety Guidelines

Current, not voltage, is what causes harm to the human body.

Safe: < 5 mA (barely perceptible)

Painful: 5-10 mA (maximum safe current)

Dangerous: > 10 mA (muscular control lost)

Lethal: > 100 mA (ventricular fibrillation)

Always follow electrical safety procedures and use proper protection.

🔬 Applications by Current Range

• fA-pA: Ion channels, molecular electronics
• nA-μA: Biosensors, low-power circuits
• mA-A: Consumer electronics, small motors
• A-kA: Industrial equipment, power systems
• MA-GA: Fusion reactors, particle accelerators
• Specialized: Medical devices, research instruments

🧮 Fundamental Relationships

Ohm's Law: I = V/R (Current = Voltage / Resistance)

Power Law: P = V × I (Power = Voltage × Current)

Charge Flow: Q = I × t (Charge = Current × Time)

AC Relationship: I_rms = I_peak / √2 ≈ 0.707 × I_peak
