A watt-hour (Wh) is a unit of energy measurement that indicates how much energy is produced or consumed over one hour at a power of one watt. It is often used to measure the energy consumption of electrical devices.
For example, if an appliance has a power of one watt and runs for one hour, it consumes one watt-hour. Similarly, an appliance with a power of 100 watts that also runs for one hour could consume 100 watt-hours (or 0.1 kilowatt-hours, since 1 kilowatt-hour = 1000 watt-hours). The watt-hour is therefore a practical unit of measurement for measuring energy consumption in the home or in industry.
In the context of cycling and fitness, the watt-hour is often used to measure the amount of energy produced or consumed during exercise.
On bicycles, particularly exercise bikes or stationary bikes in gyms, sensors can measure the power produced in watts. This measurement of power is often summed over time to calculate the total energy produced. For example, a bicycle trainer may show that a person produced 200 watts during a workout and maintained this for 1 hour. This equates to an amount of energy of 200 watt hours.
In the fitness context, the watt-hour is therefore used to quantify exercise intensity and energy expenditure. It allows athletes and fitness enthusiasts to track their performance and progress over time.
Immer mehr Menschen steigen vom Auto aufs Fahrrad um – und das nicht nur in der Freizeit. Das sogenannte Dienstrad hat sich in den letzten Jahren als attraktive Alternative zum klassischen Firmenwagen etabliert. Insbesondere E-Bikes stehen bei Arbeitnehmern und Arbeitgebern hoch im Kurs. Warum? Sie sind nicht nur nachhaltig, sondern oft auch kostengünstiger und gesünder.
In recent years, a surprising trend has taken over the streets and beaches of the Netherlands: the fat bike. The wide-tired bikes, originally designed for sandy deserts or snowy landscapes, are now a common sight in one of the most bike-friendly countries in the world. But what is behind this boom, and why is the fat bike such a good fit for Holland?
