Joules (J), Volts (V), Electric Potential & Capacitor Energy
Voltage is defined as electrical potential energy per unit charge:
- **
- Universal Joule to Volt Formulas**:
- From Electric Charge (Q in Coulombs):
V_Volts = E_JoulesQ_Coulombs
- From Capacitor Electrostatic Storage (C in Farads):
E = (1) / (2) C V^2 V_Volts = √(2 · E_Joules)C_Farads
- **
- Subatomic Energy Conversion**:
- Since 1 Coulomb = 6.241509 × 10^18 elementary charges (e):
E_eV = E_Joules × 6.241509074 × 10^18 eV
- **
- Standard High-Energy Benchmark Voltages**:
- 1.0 J / 1.0 C: 1.0 Volt (Base SI definition)
- 50 J in 800\ μF: 353.55 Volts (Xenon flash tube)
- 200 J in 50\ μF: 2,828.43 Volts (Medical cardiac defibrillator)
- 1.0 GJ / 20 C: 50,000,000 Volts (50 MV) (Natural lightning bolt)
How to Use This Calculator
Enter your Energy in Joules (J) (e.g. 1.0 or 200 for defibrillator in J), Calculation Mode — choose from From Electric Charge (Q in Coulombs: V = E / Q), From Capacitor Storage (C in µF: V = √(2E / C)), Electric Charge (Coulombs) or Capacitance (µF) (e.g. 1.0 C or 50 µF in C / µF), and Electrostatic & Medical Benchmark — choose from Custom Joules & Parameters, 1.0 Joule / 1.0 Coulomb (SI Definition) → 1.000 V, Xenon Camera Flash (50.0 J in 800 µF capacitor) → 353.55 V. Results update instantly as you type — adjust any value to compare scenarios.
The Formula
Capacitor mode: E = 0.5 C V^2 -> V = sqrt(2 * E / C)
Worked Example

Understanding Your Result
Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
