🥾 徒步时间估算Hiking Time Calculator
按距离、累计爬升和下降估算徒步用时：奈史密斯规则（5 km/h + 每爬升 600 m 加 1 小时）、加朗缪尔下坡修正，或德国/瑞士常用的 DIN 33466 方法；可加休息时间。Estimate hiking time from distance, total ascent and descent with Naismith's rule (5 km/h plus 1 hour per 600 m of ascent), with Langmuir's descent corrections, or with the DIN 33466 method used in Germany and Switzerland — plus rest stops.

奈史密斯规则是什么？What is Naismith's rule?
苏格兰登山家威廉·奈史密斯在 1892 年提出：在平路上每 5 公里（3 英里）走 1 小时，每爬升 600 米（2,000 英尺）再加 1 小时。下降不加时间。括号里的英制数字只是近似值：选英里、英尺时，本工具先按 1 英里 = 1.609344 公里、1 英尺 = 0.3048 米换算，再用公制规则计算，所以切换单位不会改变估算用时。Proposed by Scottish mountaineer William Naismith in 1892: allow 1 hour per 5 km (3 miles) on the flat, plus 1 hour for every 600 m (2,000 ft) of ascent. Descent adds nothing. The imperial figures in brackets are approximations: with miles and feet selected, this tool converts at 1 mile = 1.609344 km and 1 ft = 0.3048 m and applies the metric rule, so switching units never changes the estimate.
朗缪尔修正和 DIN 33466 有什么不同？How do Langmuir and DIN 33466 differ?
朗缪尔修正在奈史密斯基础上处理下坡：5°–12° 的缓坡每下降 300 米减 10 分钟，超过 12° 的陡坡每下降 300 米加 10 分钟。DIN 33466 按水平 4 km/h、上升 300 m/h、下降 500 m/h 分别算水平和垂直用时，总用时 = 较大者 + 较小者的一半。Langmuir adjusts Naismith for descent: subtract 10 minutes per 300 m on gentle 5°–12° slopes and add 10 minutes per 300 m on slopes steeper than 12°. DIN 33466 times horizontal travel at 4 km/h, ascent at 300 m/h and descent at 500 m/h, and the total = the larger of horizontal and vertical time + half the smaller.
休息时间怎么加？How are rests added?
「每小时休息 10 分钟」表示每走 50 分钟歇 10 分钟，总用时 = 行走用时 × 60 ÷ (60 − 休息分钟)。'10 minutes rest per hour' means 50 minutes walking then a 10-minute break, so total = walking time × 60 ÷ (60 − rest minutes).
和时区有关吗？Do time zones matter?
无关。「徒步时间估算」只计算时长，没有日期或钟点输入，也不读取设备时间，所以时区和夏令时不影响结果。No. The Hiking Time Calculator works only with durations; it has no date or clock-time input and never reads the device clock, so time zones and daylight saving time do not affect the result.
