輸入

Distance (mi or km) Efficiency (distance/unit fuel) Fuel price ($/unit)

Fuel needed (fuel units) 輸入數值後計算。

Total fuel cost ($) 輸入數值後計算。

fuel needed = distance / efficiency; total cost = fuel needed x fuel price.

此計算機用於 Estimate fuel needed and fuel cost from distance, fuel efficiency, and fuel price.

320 miles at 28 mpg needs about 11.43 gallons.

Use kilometers per liter the same way: distance divided by efficiency.

If your vehicle uses L/100 km, convert it before using this version.

What inputs does this calculator need?

Distance, Efficiency, Fuel price.

How should I round the result?

Keep extra digits while comparing values, then round for the final decision or report.

Can I reuse the result in another calculation?

Yes, but preserve the original inputs and units so the next calculation stays traceable.
