Estimate Electricity Usage
Formula for “Estimate Electricity Usage”
To estimate electricity usage, we use the following formula:
Electricity Usage (kWh) = (Wattage × Hours Used per Day × Number of Days) ÷ 1000
- Wattage = Power consumption of the device in watts
- Hours Used per Day = Average daily usage in hours
- Number of Days = Total days of usage
- 1000 = To convert watt-hours to kilowatt-hours (kWh)

What Is Electricity Usage?
Electricity usage means how much electrical energy a device or system uses. We measure it in kilowatt-hours (kWh). One kilowatt-hour is the energy used by a 1000-watt device running for one hour.
In textile factories, we run many machines for long hours. We must measure electricity usage to save energy and reduce costs.
Example from a Textile Factory
A sewing machine uses 200 watts. It runs for 8 hours a day, 30 days a month.
Usage = (200 × 8 × 30) ÷ 1000 = 48 kWh per month.
This simple formula works for any device at home or in factories.
Why Textile Engineers Estimate Electricity Usage
Textile factories use many types of electrical machines. These include spinning machines, dyeing machines, sewing machines, compressors, and air conditioners. Each machine uses electricity every day.
As a textile engineer, I use electricity data to:
- Cut power costs
- Choose energy-efficient machines
- Schedule machine use during low-rate hours
- Compare monthly bills with estimated usage
These steps help factories save money and avoid waste.
How to Use an Electricity Usage Calculator
We created a simple calculator based on the formula. Users just input:
- Device wattage
- Daily usage hours
- Number of usage days
Then click "Calculate" to get the estimated usage in kWh.
Best Uses in the Textile Industry
In my factory, I use the calculator before buying new machines. I also use it to check if the bill matches actual usage. When a bill is high, I use the calculator to find which machine is using more power than expected.
Real-Life Use in a Textile Factory
In my work, I once faced a power bill that was 20% higher than usual. We used the calculator to check each machine. We found that one old drying machine was using 1.5 times more power than expected. After replacing it with a new one, our monthly bill dropped by 18%.
This proves the value of tracking and estimating usage.
Benefits of Estimating Electricity Usage
Estimating electricity usage has many benefits:
- Saves money
- Extends machine life
- Supports factory planning
- Reduces carbon emissions
- Matches energy demand with supply
Factories that monitor energy can make better decisions.
Upcoming Trends in Electricity Usage Monitoring
Many textile industries now use smart meters and sensors. These track real-time usage. Data is sent to a central system for review.
As a fashion designer and textile engineer, I also see new designs that focus on sustainability. Low-power lighting, smart climate control, and high-efficiency motors are now common in modern textile units.
Conclusion
Electricity is a major cost in textile production. We must estimate and manage usage carefully. The formula is simple. The calculator helps with fast results. With accurate estimation, we can cut costs, save power, and improve factory performance.
Factories, homes, and offices can use the same method. All you need are three values: wattage, daily hours, and number of days. Try the calculator and start saving electricity today.
