MPG Viewer

Purpose and scope: MPG Viewer converts distance and consumption data into fuel-economy metrics for drivers, fleets, and analysts. It handles both US and metric units and outputs standard indicators such as MPG and liters per 100 kilometers when requested.
Core calculations: The primary formula is MPG = miles / gallons. It supports distance units miles or kilometers and volume units US gallons or liters, with optional metric conversions. Input validation enforces positive numeric values and sensible unit selections. Advanced mode enables L/100km output and batch processing for multiple trips. Outputs are numeric values with controlled precision for reporting.
Data flow: Users supply numeric inputs with associated units. The tool normalizes units, applies the MPG formula, and, if metric mode is enabled, computes L/100km using the relation L/100km = 235.214583 / MPG. Results are presented in a consistent format suitable for dashboards and reports. Use cases span quick trip checks, fleet performance comparisons, and driver training on fuel efficiency. Differentiators include explicit unit handling, clear validation rules, and minimalism focused on transparency of calculations rather than data storage or forecasting.
