Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It's measured in coulombs (C) in the SI system. One coulomb equals the charge transported by a constant current of one ampere in one second. Other units include ampere-hours (Ah) for batteries, elementary charge (e) for atomic-scale calculations, and statcoulombs in the CGS system.

Frequently Asked Questions
Electric current measures the flow of electric charge. The SI unit is the ampere (A). To convert between units, use our Current Converter: select your source unit (e.g., milliamperes), enter the value, choose the target unit (e.g., amperes), and get instant results. Common conversions: 1 A = 1000 mA = 1,000,000 μA = 0.001 kA.
Electric potential, commonly called voltage, is the electric potential energy per unit charge. It's measured in volts (V). One volt equals one joule per coulomb. Voltage represents the work needed to move a charge between two points. Our converter handles volts, millivolts, microvolts, kilovolts, megavolts, and CGS units like abvolts and statvolts.
Resistance (measured in ohms, Ω) opposes current flow, while conductance (measured in siemens, S) facilitates it. They are reciprocals: G = 1/R. A high resistance means low conductance and vice versa. Our tools convert both independently. For example, 1 Ω = 1 S⁻¹, and 1 kΩ = 0.001 S.
Inductance is the property of an electrical conductor that opposes changes in current. It's measured in henries (H). Inductors store energy in magnetic fields and are essential in transformers, motors, generators, and filters. Our converter handles henries, millihenries, microhenries, nanohenries, and CGS units like abhenries and stathenries.
Yes, our converters use scientifically-verified conversion factors from the International System of Units (SI) and NIST standards. Results are accurate to 10 significant digits, suitable for engineering calculations, scientific research, academic work, and professional applications. All factors are regularly updated to match the latest metrology standards.
Yes. Once the page loads, all calculations happen locally in your browser. There is no server-side processing, no API calls, and no internet dependency for conversions. This makes the tools perfect for laboratories, field work, remote locations, and anywhere connectivity is limited or unavailable.
Capacitance is the ability of a system to store electric charge. It's measured in farads (F). One farad equals one coulomb per volt. Capacitors store energy in electric fields and are used in filtering, timing circuits, and energy storage. Our converter handles farads, microfarads, nanofarads, picofarads, and CGS units.
Absolutely. Our converters are designed with a mobile-first responsive approach and work perfectly on every device — from basic keypad phones to 4K desktop displays. The interface adapts intelligently: desktops get a sidebar, tablets get a collapsible sidebar, and mobile devices get optimized dropdowns. Touch interactions and momentum scrolling are optimized for mobile.
No. We do not collect, store, or transmit any of the values you enter. All calculations happen entirely in your browser's memory and are destroyed the moment you close the tab. We use no analytics scripts, no cookies for tracking, and no third-party services that could see your conversions. Your privacy is absolute and non-negotiable.
Electric field strength measures the force per unit charge experienced by a test charge in an electric field. It's measured in volts per meter (V/m). This is crucial for electromagnetic compatibility (EMC) testing, antenna design, and safety assessments. Our converter handles V/m, kV/m, V/cm, and CGS units.
