Which is more important in a Leaf Blower CFM or MPH? Don’t blow your peace away thinking about your leaf blower, as we’re here today, presenting the differences between Leaf Blower CFM vs MPH. Whatever, it’s a battery-operated blower or electric.
However, The answer to your question is not going to be just one word; rather, it’s a bit complicated. You’ll see what we mean further into the article!
What is CFM on Leaf Blowers?
You might have come across the term CFM before, so it basically stands for cubic feet per minute. And leaf blower CFM means how much air is propelled out of the leaf blower over a minute.
For context, a 250 CFM device will push out two hundred and fifty cubic ft of air per minute.
What is a Good CFM for a Leaf Blower?
The CFM of a leaf blower shows how much power it has to move stuff around. So, leaf blowers with larger CFM ratings will generate more power than the ones with a smaller CFM rating. The CFM that will be good for you widely depends on the size of your backyard and how heavy the work you are doing.
A leaf blower with a 500+ CFM rating can move a heap of fronds and even tiny rocks while an 800 CFM rating leaf blower will allow you to move small rocks and even some sticks.
It’s important to stay cautious and safe when you are using a high CFM rating leaf blower with people around you. Generally, the range that will be considered good for a handheld device is 350-600 CFM. It should be ample to get ordinary tasks done with ease.
For an average-sized backyard, a 200-400 CFM rating electric leaf blower would be plenty for you.
However, if your backyard is any more than a half-acre you will need to grab a 400-700 CFM rating leaf blower. These create more noise, but on the upper hand, they are quite a bit more powerful, allowing you to clear out dry and also wet debris.
On the other hand, if you’re working on a huge commercial space, then you will have to get something more powerful than 1000 CFM.
What is MPH on a Leaf Blower?
MPH stands for miles per hour, and it is one of the most common measurements of speed. It is used for car speed, wind speed, and anywhere with speed, universally. We are certain that you know what it means, but still, we’ll break it down for you.
MPH means how many miles something will go if it moves at that steady rate for an hour. Just like the example with CFM, air pushed out at 200MPH means that the gush of air is pushed at a distance of 200 miles away in an hour if the speed is maintained.
What is the Difference Between Leaf Blower CFM vs MPH?
CFM and MPH aren’t synonyms for the same term; in fact, they’re quite different from each other. CFM has more to do with power, and MPH is entirely about speed.
Air moving at a high velocity can instantly lead you to believe that it also has high power. Although high-speed air most of the time has higher power, that doesn’t need to be the case always. They are not correlated.
Do not make the mistake of buying a high MPH leaf blower and automatically assuming that it’ll be very strong, that’s just not how it works. A leaf blower with low MPH can be stronger than one with double the MPH rating; it all depends on the CFM rating.
If you’re looking to move away from a large volume of leaves and debris, then you should definitely opt for a high CFM rating leaf blower.
Do keep in mind though that the highest CFM leaf blower will be larger and noticeably heavier than your regular ones. To get your work done in half the time, you would have to trade off your comfort.
With saying all that, do not think you’ll be fine with 10,000 CFM, and only 15 MPH. CFM is more about power than MPH, but you also need speed to move away from all that junk. There needs to be a good balance between both for you to achieve satisfactory results.
The real question that stands is what is the perfect measure you should be looking for? Or is there even a perfect balance?
The question to that answer is a big ‘YES‘.
Measure leaf blower power
When it comes to leaf blowers, more power isn’t always better. In fact, a leaf blower with too much power can be difficult to control and may end up doing more harm than good. But how do you know if a leaf blower has enough power for the job? Here are some factors to consider when measuring leaf blower power.
The amount of air flow is perhaps the most important factor in determining whether a leaf blower has enough power. Measured in cubic feet per minute (CFM), airflow tells you how many leaves the leaf blower can move in a given time period. A general rule of thumb is that the higher the CFM, the better.
However, keep in mind that CFM alone doesn’t tell the whole story. It’s also important to consider wind speed (measured in miles per hour or MPH).
Also known as wind speed, this measures how fast air moves through the nozzle of the leaf blower and is typically measured in miles per hour (MPH). A higher airspeed will create a powerful stream of air that can quickly move leaves and debris.
However, too high of an airspeed can also be detrimental. It can cause light objects like twigs and pollen to fly around erratically, making them difficult to control. That’s why it’s important to find a balance between airflow and airspeed when selecting a leaf blower.
Another factor to consider when measuring blower power is weight. A heavier machine may be more difficult to maneuver, but it will usually have more power than a lighter one. If you plan on using your leaf blower often, look for one that strikes a good balance between weight and power.
The size of the leaf blower’s nozzle also plays a role in its power. A larger nozzle will allow more air to flow through, while a smaller nozzle will create a more focused stream of air. If you need to move large amounts of leaves or debris, look for a leaf blower with a large nozzle.
Now that you know how to measure leaf blower power, it’s time to find the right machine for the job. Keep these factors in mind and shop around until you find a model that meets your needs.
More understanding of leaf blower CFM and mph – let’s watch this video
Anyway, when we are talking about power and force systems we should know the basics of Newton’s law!
What is Newton’s Force?
When you’re down in the store and comparing blowers, you should simply be looking at the Newton force to make your life easier. So, it’s basically a combination of both CFM and MPH. The effects of these are actually put into a single measurement, allowing you to understand how much force it creates.
Tests have provided results that show blowers that are cordless produce force ranging from about 9-16 NM (NM- Newton Meters), while the larger and more powerful ones produce a force in the range of 29-38 NM.
The measurement of Newton’s force really removes all your headaches because it’s just that simple to get into your head. The bigger the Newton force, the better it will get your chores done.
Keep in mind though, that just buying a device with a high Newton force will not get you the best results, you must also follow proper techniques of leaf blowing.
Let’s, read out something crazy science or you may call it off-topic: About Force and Acceleration Experiment: (may you skip this if you know already)

Newton’s 2nd law of motion – Newton’s Laws of motion – has been a long-standing standard for examining
mechanics in classical situations. The second law in particular is of great use and importance.
You probably recognize this law in the form F=ma (force is the product of mass times acceleration), but
Newton himself stated “A change in motion is proportional to the motive force impressed and takes place
along the straight line in which that force is impressed (Philosophize Naturalism Principia Mathematica).”
Mathematically, this law is generally expressed as the force being the time derivative of momentum. But then
where does this F= ma come from?
To answer that, we start with the momentum formulation,

Calculate newton force leaf blower
Well, now you can calculate the Newton force of your leaf blower with this simple formula:
Newton Force = Leaf Blower Airspeed (m/s) x Leaf Blower Airflow (kg/s)
To use this formula, simply plug in the airspeed and airflow values for your leaf blower. The resulting number will tell you the Newton force exerted by your leaf blower.
So, if you want to know how powerful your leaf blower is, simply calculate its Newton force!
