骑行功率体重比计算器
在骑行运动中，每千克瓦特数（W/kg）在每一次爬坡和每一场计时赛中都比绝对功率更重要。输入你的 FTP 或持续功率以及体重，这个计算器会以 W/kg 和 W/lb 给出你的功率体重比，并显示对应的骑手等级。用它来跟踪训练进展、对照标准成绩区间，或查看减重或提升功率会如何改变你的比率。
功率体重比（W/kg）是骑行运动中最能预测爬坡和计时赛成绩的单一指标。它等于你的可持续功率除以体重，因此提高功率或降低体重都能改善它。所示区间适用于20分钟功率或FTP功率：大致低于2.5为休闲，2.5至3.5为受过训练，3.5至4.5为优秀，4.5至5.5为非常优秀，超过5.5 W/kg为精英。请使用FTP以获得最有意义的对比。
常见问题
- What is cycling power-to-weight ratio?
- Power-to-weight ratio is your sustainable power output divided by body weight, expressed in watts per kilogram (W/kg). It strongly predicts climbing and overall road-cycling performance, since a lighter rider producing the same watts accelerates and climbs faster.
- How do I calculate my W/kg?
- Divide your power, usually your FTP, by your body weight in kilograms. For example, 280 W at 70 kg is 4.0 W/kg. Enter your FTP or power and weight, and the calculator returns your ratio along with an indicative rider category.
- What is a good power-to-weight ratio?
- At FTP, recreational riders are often around 2-3 W/kg, strong amateurs reach 3.5-4.5 W/kg, and elite or professional riders exceed 5-6 W/kg. Categories vary by sex and effort duration, so treat the rating as a guide rather than a strict cutoff.
