This calculator uses the average watt rating (100 Watts) for a Clock. You can input your Clock’s details to calculate the exact usage and cost of your device.
Enter how many hours per day you estimate you run your Clock. If it is less than one hour use a decimal. For example, 30 minutes would be .5 and 15 minutes would be .25.
Input the wattage of your Clock. If you are unsure enter the average wattage for a Clock: 0.
The average Clock uses 0 watts. Your devices wattage may be different depending on the brand, size, or other factors. You can generally find the wattage of your Clock in the user manual or on the device itself.
Enter the price per kilowatt-hour (kWh) you pay for electricity. If you are unsure you can use the average rate per kWh in the US (10 cents) or find the kWh rate in your area here.
Clocks are timepieces that measure and display the passage of time. Humans have been measuring time in various ways for millennia, including tracking the sun's movements with sundials, using water clocks, candle clocks, and hourglasses.
Our current system of using a base-60 time system, which is a clock with 60-minute and 60-second increments, dates back to 2,000 B.C.
During the 14th century, the first mechanical clocks were invented in Europe and were the standard timekeeping device until the invention of the pendulum clock in 1656. Many parts came together to form the modern-day timekeeping pieces we have today.
Ancient Egyptians used Obelisks, built around 3,500 B.C., and were among the first shadow clocks. Egypt has the oldest known sundial dating back to around 1,500 B.C. Sundials evolved from shadow clocks, the first devices used to measure the hours of the day.
Even before the birth of the modern clock that people worldwide use, other countries have their versions of measuring time, day, week, month, and years. After the development of agriculture stopped ancient civilizations from moving from place to find food, ancient people developed a calendar system to track the crops and when they will be harvested.
As time passed, technology evolved, and by the 15th century, there had been developments on the clock like wrist watches, pocket watches, etc. By the 17th century, a mechanical alarm clock had been created. One widely depicted clock that is shown in movies or cartoons is the pendulum clock, especially with the cuckoo bird.
Loud and blaring alarm clocks were still not invented during the early 18th century. For people to be woken up early, they would hire someone to knock on their doors/windows to wake them called a knocker-upper.
A knocker-upper was a member of a profession that began during and lasted well into the Industrial Revolution in Britain and Ireland when alarm clocks were neither cheap nor reliable. A knocker-job up's was to wake people who were sleeping so they could get to work on time.
As technology evolves, so does the development of a clock, from battery-operated to an electrical clock. A battery-operated clock can be inconvenient since you need to replace the battery when it runs out. The electric clock is more convenient as it doesn't need replacement now and then.
But unlike other electricity-powered appliances that can be turned off when not in use, an electric clock runs 24/7 to keep track of the time. So, how much electric usage of a clock costs on your electric bill?
If you want to know the power consumption of the electric clock you bought, you should look at the label on the bottom or back of the device or appliance for the electricity usage monitor.
An electric clock wattage is about 3 watts, and a digital clock is used almost 24 hours a day on average. You can use it as your alarm clock to wake you up in the morning with loud music or a bell. Compare to other electrical appliances, it doesn’t really have a high electricity consumption.
If you decided to choose a LED electric digital clocks, use an electronic power supply, either AC power from a wall outlet or a battery. A digital clock's display typically employs one of two types of lights. The lighted time will be displayed using either Light Emitting Diodes (LED) or a Liquid Crystal Display (LCD).
Electromechanical clocks use electricity to rewind the mainspring to keep time with an oscillating pendulum or balance wheel powered through a gear train by a mainspring.
Electric remontoire clocks have gear trains that are turned by a remontoire, which is a small spring or weighted lever that is wound up more frequently by an electric motor or electromagnet.
Electromagnetic clocks use a pendulum or balance wheel to keep time. This mechanism was used in the first electric clocks and can still be found in antique electric pendulum clocks. It can also be found in a few contemporary decorative mantels and desk clocks.
By driving the clock gears with a synchronous motor, Synchronous clocks use the 50 or 60 Hz utility frequency of the AC electric power grid as a timing source. They essentially count power supply cycles.
This was the most common type of clock until the 1930s, when quartz clocks took over.
Quartz clocks are electric timepieces that keep track of time by counting the oscillations of a vibrating quartz crystal. They use modern low-voltage DC-powered circuitry that can be powered by a battery or by mains electricity. They are currently the most common type of clock.
Radio-controlled clocks are quartz clocks that are synchronized with the UTC atomic clock time scale regularly using radio time signals broadcast by dedicated stations around the world.
They differ from clock radios.
Digital clocks are easier to read in stressful, time-sensitive situations, and some digital models include a countdown timer to help people keep track of the time. Regardless, clocks are essential in our daily lives; choose the right type of clock for your household to avoid missing important happenings around you.
