This image is a quick reference chart for Essential Electrical Unit Conversions. It lists the most common electrical, power, energy, frequency, temperature, length, and time conversions used in electrical engineering and electronics. 1. Electrical Units These are the basic electrical conversions: 1 kV = 1000 V (Kilovolt to Volt) 1 V = 1000 mV (Volt to Millivolt) 1 A = 1000 mA (Ampere to Milliampere) 1 kA = 1000 A (Kiloampere to Ampere) 1 MΩ = 1000 kΩ (Megaohm to Kiloohm) 1 kΩ = 1000 Ω (Kiloohm to Ohm) 1 µF = 1000 nF (Microfarad to Nanofarad) 1 nF = 1000 pF (Nanofarad to Picofarad) 1 Ω = 1 V/A (Ohm's Law definition) 1 S = 1/Ω (Siemens is the unit of conductance) 2. Power Conversions These show how different power units relate. 1 kW = 1000 W 1 MW = 1000 kW 1 GW = 1000 MW 1 VA = 0.001 kVA 1 kVA = 1000 VA 1 MVA = 1000 kVA 1 HP = 746 W 1 kW ≈ 1.341 HP 3. Energy Conversions These are used for electrical energy calculations. 1 Wh = 3600 J 1 kWh = 1000 Wh 1 MWh = 1000 kWh 1 GWh = 1000 MWh 1 J = 0.239 cal 1 cal = 4.186 J 1 kWh = 3.6 MJ 4. Frequency Conversions Used in AC power systems and electronics. 1 kHz = 1000 Hz 1 MHz = 1000 kHz 1 GHz = 1000 MHz 5. Temperature Conversions Common formulas for converting temperature. °C = (°F − 32) × 5/9 °F = (°C × 9/5) + 32 K = °C + 273.15 6. Length Conversions Useful for cable measurements. 1 km = 1000 m 1 m = 100 cm 1 m = 1000 mm 1 inch = 25.4 mm 1 ft = 0.3048 m 7. Time Conversions 1 hour = 60 minutes 1 minute = 60 seconds 1 hour = 3600 seconds Notes (Unit Symbols) V = Volt A = Ampere Ω = Ohm W = Watt kW = Kilowatt kVA = Kilovolt-Ampere Wh = Watt-hour kWh = Kilowatt-hour Hz = Hertz HP = Horsepower S = Siemens J = Joule m = Meter cm = Centimeter mm = Millimeter k = Kilo (1,000) M = Mega (1,000,000) G = Giga (1,000,000,000) Summary This chart is a handy reference for electricians, electrical engineers, and electronics technicians. It helps quickly convert units used in electrical circuits, motors, transformers, power systems, and electronic devices. #Electronics #foryou #ElectronicsExplained #CircuitDesign #basicelectronics
