MWh to GJ Converter

About This Tool

This tool provides precise, bidirectional conversions between megawatt-hours (MWh) and gigajoules (GJ) for energy professionals, researchers, project planners, and students who work with energy data. It is used when reporting energy demand, capacity, or consumption in a preferred unit, performing quick reconciliations between measurement standards in reports, models, or audits.
Conceptually, energy units are related by a fixed factor: 1 MWh = 3.6 GJ. The tool applies this exact factor in both directions, so MWh → GJ is multiply by 3.6 and GJ → MWh is divide by 3.6. The calculation is a straightforward arithmetic operation with no external data dependencies, enabling fast, reproducible results for consistent datasets.
Audience and value: engineers, energy analysts, students, and planners gain speed, accuracy, and reproducibility in energy budgeting and reporting. Unique differentiators include a minimal input surface, clear two-way conversions, and strict validation to prevent invalid data from propagating into calculations.
Core features and use cases: inputs consist of value, from_unit, and to_unit (restricted to MWh and GJ); outputs return the converted value with the target unit. Use cases include converting project energy requirements, validating supplier data, and harmonizing datasets from different sources. Example: 5 MWh equals 18 GJ; 18 GJ equals 5 MWh.
