Watt-seconds to Watt-minutes conversion

How to convert watt-seconds to watt-minutes?

To convert watt-seconds (Ws) to watt-minutes (Wmin), you need to understand the relationship between seconds and minutes. Since there are 60 seconds in a minute, to convert from watt-seconds to watt-minutes, you divide the number of watt-seconds by 60.

Here’s the conversion formula:

$\text{Wmin} = \frac{\text{Ws}}{60}$

So, to convert 1 watt-second to watt-minutes:

$1 \, \text{Ws} = \frac{1}{60} \, \text{Wmin} \approx 0.0167 \, \text{Wmin}$

Examples for other quantities of watt-seconds:

1. 60 watt-seconds:

$60 \, \text{Ws} = \frac{60}{60} \, \text{Wmin} = 1 \, \text{Wmin}$

This means that 60 watt-seconds (equivalent to 1 Watt-minute) is the energy of a 1-watt device running for 1 minute.

2. 120 watt-seconds:

$120 \, \text{Ws} = \frac{120}{60} \, \text{Wmin} = 2 \, \text{Wmin}$

This means that 120 watt-seconds (or 2 Watt-minutes) is the energy of a 1-watt device running for 2 minutes, or a 2-watt device running for 1 minute.

3. 600 watt-seconds:

$600 \, \text{Ws} = \frac{600}{60} \, \text{Wmin} = 10 \, \text{Wmin}$

This means that 600 watt-seconds (or 10 Watt-minutes) is the energy of a 10-watt device running for 1 minute, or a 1-watt device running for 10 minutes.

Real-world examples:

1. Energy used by a small LED light:

If a small LED light uses 1 watt of power, and it is kept on for 10 seconds, it consumes 10 watt-seconds of energy.

$10 \, \text{Ws} = \frac{10}{60} \, \text{Wmin} \approx 0.167 \, \text{Wmin}$

2. Charging a small battery:

If a small battery charger outputs 2 watts of power, and it operates for 300 seconds, it uses 600 watt-seconds of energy.

$600 \, \text{Ws} = \frac{600}{60} \, \text{Wmin} = 10 \, \text{Wmin}$

3. Powering a small electronic device:

If a small electronic device with a power requirement of 5 watts operates for 12 seconds, it uses 60 watt-seconds of energy.

$60 \, \text{Ws} = \frac{60}{60} \, \text{Wmin} = 1 \, \text{Wmin}$

These examples illustrate how watt-seconds can be used to quantify the energy consumption of various electrical devices over different periods.
