Watts to Hours Formula:
From: | To: |
The Watts to Hours calculation determines how long a device can run based on its energy storage (watt-hours) and power consumption (watts). This is essential for battery life estimation and power management.
The calculator uses the simple formula:
Where:
Explanation: The formula divides the total energy available by the rate of energy consumption to determine runtime.
Details: Accurate runtime calculation is crucial for battery-powered devices, energy planning, and understanding power consumption patterns.
Tips: Enter energy in watt-hours and power in watts. Both values must be positive numbers. The result shows how many hours the device can run at the specified power level.
Q1: What's the difference between watts and watt-hours?
A: Watts measure power (rate of energy use), while watt-hours measure energy (power × time).
Q2: Can I use this for battery life estimation?
A: Yes, if you know the battery's capacity in Wh and the device's power draw in W.
Q3: How accurate is this calculation?
A: It provides theoretical maximum runtime. Real-world factors like efficiency losses may reduce actual runtime.
Q4: What if my device power varies?
A: Use average power consumption for estimation, or calculate for different power levels.
Q5: Can I convert hours to minutes or seconds?
A: Yes, multiply the result by 60 for minutes or 3600 for seconds.
