What is the ETA Calculator?
The Time of Arrival (ETA) Calculator estimates when you will reach your destination based on the distance you need to cover, your average travel speed, your departure time, and any planned stops or breaks. It is ideal for road trips, deliveries, cycling, running, or any journey where you want a realistic arrival time on a 24-hour clock.
How to use it
Enter the total distance in kilometres, your average speed in km/h, the hour and minute you depart (24-hour format), and the total minutes you expect to spend stopped (fuel, food, rest). The calculator returns your ETA, the pure driving time, and the total trip duration including stops. If the trip crosses midnight, it shows how many days later you arrive.
The formula explained
Travel time equals distance divided by speed:
Worked example
Driving 500 km at 80 km/h gives ((500) ÷ (80)) = 6.25 hours = 375 minutes of driving. Add 45 minutes of stops for 420 minutes total. Leaving at 22:00 (1320 minutes), the arrival is 1320 + 420 = 1740 minutes. Dividing by 1440 gives 1 full day over, with a remainder of 300 minutes = 05:00. So you arrive at 05:00 the next day.
使用注意事項與精準校對原則(6 大核心守則)
📐 1. 嚴格對齊輸入量綱與單位
輸入各項數值時請務必確認量綱(例如小時、天數、金額、百分比),避免單位不匹配引發推算偏差。
🔒 2. 純前端本機毫秒級隱私保障
所有計算邏輯 100% 在您的終端瀏覽器內完成,資料絕不上傳伺服器,嚴格守護商業與個人隱私。
📊 3. 符合公認學術與產業計算模型
演算法嚴格遵循國際通用數學公式與標準計算模型,經多重情境交叉核對,數值嚴密精確。
📋 4. 一鍵複製與免登入 PDF 匯出
支援一鍵複製推算結果字串至剪貼簿,亦可直接點擊列印按鈕輸出純淨 PDF 工作報表。
🔄 5. 多情景敏感度動態對比
建議針對極端值與多組預期情景分別試算,觀察輸出數據的波動區間,輔助做出更穩健的決策。
