Convert Power from Megawatts to British thermal units per second (MW to Btu/s)

What is a Megawatt (MW)?

A megawatt (MW) is a unit used to measure power.

It's equal to one million watts.

To put it simply, it's a way to describe a huge amount of electricity being used or generated at a single moment.

How Many Homes Can 1 MW Power?

One megawatt (1 MW) can power between 750 and 1,000 homes at any given moment.

This number can change depending on what's running in each home (like air conditioning on a hot day).

It's a helpful estimate used by grid operators to understand how much electricity a community needs.

The Difference: Megawatt (MW) vs. Megawatt-hour (MWh)

It's easy to mix up megawatts (MW) and megawatt-hours (MWh). Here's a simple way to understand the difference between MW vs. MWh:

• Megawatt (MW) measures power, or how fast energy is being used right now. Think of it as the speed of electricity.
• Megawatt-hour (MWh) measures energy, or the total amount of electricity used over a period of time. This is the volume of electricity used.

So, a power plant has a capacity measured in MW (how much electricity it can make at once).

In contrast, your electricity bill shows your consumption in MWh (how much you actually used over a month).

How Big is a Megawatt? Real-World Examples

A megawatt is a tremendous amount of power. To understand its scale, here's a look at the capacity of different power sources:

• Onshore Wind Turbine: 2 to 5 MW
• Utility-Scale Solar Farm: 50 to 500 MW
• Modern Nuclear Power Plant: Over 1,000 MW (which is 1 gigawatt or GW)

What is a British thermal unit per second (Btu/s)?

The British thermal unit per second (Btu/s) is a unit used to measure power in the imperial system of measurement.

Think of it as a way to quantify how much heat energy is being transferred in a single second. For context, one Btu/s is equal to about 778.17 foot-pounds per second (ft-lb/s).

The plural form is "British thermal units per second."

How to Convert Btu/s to Watts

A common question is how Btu/s relates to the watt, which is the standard (SI) unit of power. The conversion is straightforward and very useful for comparing equipment specifications.

• 1 Btu/s is equal to approximately 1,055.06 watts (W).
• This is the same as 1.055 kilowatts (kW).

This conversion is essential for anyone needing to compare the power of different systems, especially when analyzing energy use or heat output.

Where is Btu/s Used? Common Applications

You'll most often see Btu/s used in high-power industrial and scientific settings to measure the rate of heat energy transfer.

It's a key measurement for specifying the performance of powerful equipment, such as:

• Industrial boilers
• Large-scale heat exchangers
• Power plant turbines

While you might see Btu/h (Btu per hour) used for your home's HVAC system or water heater, Btu/s provides a much more detailed, second-by-second measurement needed for these high-capacity industrial applications.

Btu/s vs. Horsepower: What's the Connection?

In engineering, Btu/s is also directly related to horsepower (hp), another common imperial unit of power.

This connection is vital for understanding the thermal efficiency of engines—in other words, how well an engine converts heat into mechanical work.

The relationship is:

• Approximately 0.7068 Btu/s is equal to 1 mechanical horsepower (hp).

This allows engineers to compare the heat an engine produces (in Btu/s) to the mechanical power it puts out (in horsepower).
