Battery use and Wh-per-mile calculator

Enter distance and observed energy use to calculate Wh/mile and an illustrative battery range with a reserve.

Turn a real ride into a planning number.

Only enter watt-hours consumed if your bike, meter or test provides that figure. Battery-bar icons and uncalibrated percentages are not accurate Wh measurements.

Trip distance (miles) Measured energy consumed (Wh) Nominal battery capacity (Wh) Planning reserve (%)

Energy used per mile—

Range based on that ride—

Energy available after reserve—

Consumption can change with wind, hills, tire pressure, load, rider effort and battery conditions.

This assumes reported energy use is measured and the entered battery capacity is available under those conditions; real usable energy may be lower. No battery diagnosis or laboratory claim is implied.
