About This Tool
This tool performs bidirectional conversions between electrical charge (Ah) and energy (kWh) using a supplied voltage. It targets engineers, technicians, and researchers who size batteries, estimate runtime, or budget energy consumption.
Conceptually, Watt-hours = Ampere-hours × Voltage, and Kilowatt-hours = Watt-hours / 1000. The tool applies these formulas to user-provided inputs and returns the requested unit with precision. For example, at 12 V, 50 Ah yields 0.6 kWh (50 × 12 / 1000). It supports both directions: Ah→kWh and kWh→Ah.
Core value lies in its simplicity and correctness: no assumptions about efficiency or AC losses; it provides quick equivalence checks during design, testing, or procurement.
How to Use
1. Provide inputs: value, voltage, from_unit, and to_unit.
2. Ensure units are Ah or kWh and voltage is in volts.
3. Run calculation: the tool applies the standard formulas and returns the result.
4. Review outputs: verify the unit and numeric precision.
5. Adjust inputs if needed: change voltage or direction to inspect different scenarios.
6. Copy or export result if required.
