No. It isn't meant to be used that way. It won't be at all accurate - and from your other post it doesn't sound like the one you have is accurate even when used during exercise. A heart rate monitor is meant to be used during steady elevated heart rate cardio and tells your heart rate - not actually calories burned.3

A heart rate monitor can't even tell you how many calories you burn when you exercise let alone when you eat dinner. Besides, is every day in your life exactly the same?2

Myfitnesspal gives you an ESTIMATE. That's the best that your heart rate monitor will be able to do.
Chances are, some of the online TDEE and BMR calculators will give you an estimate similar to a heart rate monitor.
Wearing a HRM for one day isn't going to give you a lot of useful information. It's best to use them specifically during cardio exercise, and use it as a TOOL to estimate your fitness, not necessarily as a diet/weight loss tool.4 -

I will wear only for one day
It won't matter how long you wear it - it's not designed to be used that way at all.
A heart rate monitor takes the info you plugged in height, weight, etc. Then it makes assumptions based on that data. Then a heart rate monitor takes a reading of your resting heart rate.
When you wear a heart rate monitor (during steady state cardio exercise) it compares your resting heart rate against your exercise heart rate. Then it uses ONE formula (and the assumptions) from above to calculate an estimate of your exercise calories.
It's still assumptions and estimates......even when used properly.2 -

But then how much do i burn in walking..if i m 173 pounds female 5.2 height age ia 35..pls calculate for me
Just pick an estimate, go with it, and adjust based on your real life results. That's what many successful people here have done. Stop thinking you have to get everything perfect before you get started.
You've got an estimate, just work with that.4 -
The calories burned estimates from HRMs are only useful when doing cardio exercises, not even strength training, much less every day life.
You've started a lot of threads with really basic questions, I'd suggest reading the sticky/important threads and use the tool as intended.
Nobody can tell you how many calories you burned walking. Depends not only on your size and weight but also your intensity, distance, etc. got HRM probably does the best job of estimating this if it is set up properly.0 -

No...there is no direct relationship between energy expenditure and your hear rate. They can provide a reasonable estimate of energy expenditure during a steady state aerobic event, but it's not "exact."
A HRM uses your HR in an algorithm to estimate some % of VO2 max that you're working...as such, the algorithm also assumes a more or less steady state aerobic event as would be required to estimate your VO2 max. They are pretty much worthless for estimating energy expenditure if your HR is below the aerobic threshold or above it.0 -

The key here is having a quality HRM and associated gear that is properly set up and given the most accurate biological information. A chest HRM is MUCH more accurate than anything worn on the wrist. I have used polar products for years as for HRM purposes they are the gold standard. For other uses other companies are better.
When you put all the information together you can start to get a reasonably accurate picture of what is going on, but it isn't exact and requires diligence to keep the Biological information set up and accurate.
Here is the main equipment I use. An M430 Running watch, an H10 Chest HRM and a V650 cycling computer. Not pictured are speed and cadence sensors installed on my bike.
Hope this is helpful.

Wow...tough crowd! A heart monitor with a chest strap is going to be *more* accurate than any monitor that tries to go off of the pulse on your wrist. Unfortunately there isn't going to be anything that would be 100% accurate. You could try it for a day to get a rough estimate and something to go off of, but like the others said, it may not be to a "T". You may walk more one day then the next, etc. And you will wear the batteries down (big deal, right?). I have researched the same thing online, because I too was curious if it would give you an accurate count of daily burn. I say go for it if it will give you a base line to go off of. You can always tweak your calorie intake or exercise intensity if you feel like it isn't working. It has been proven that the chest strap monitors are nearly as accurate as having an EKG performed. Give it a shot. The worst you may be out is the cost of batteries that need to be replaced. Best of luck to you.10

How is it a tough crowd...a HRM isn't designed to be worn all day to estimate energy expenditure. Something like a FitBit or other activity tracker is, but it's still an estimate. There is a difference between a HRM and an activity tracker like a Fitbit...using a HRM like a Fitbit is useless.4 -

This is false information. While exercising, a monitor with a chest strap is going to give you a very accurate calorie burn, as well as keep you in your targeted heart rate zone.8 -

No...it's going to give you a reasonable estimate provided you are doing more or less steady state aerobic activity...an actual HRM is worthless for measuring energy expenditure if you are anywhere outside of the aerobic zone...either under or over.
I would say it's a reasonable estimate for an aerobic event...not "very accurate"...just reasonable.7 -

Where does that say that a HRM is accurate when being worn all day - which is what the OP is asking?8 -

We're not talking about wrist vs chest strap...the OP is talking about wearing a HRM all day...they don't work like that.
Not that I haven't been doing this for a very long time or anything like that...7 -

A heart monitor with a chest strap was never designed to give an estimate for calories burned all day. It's for specific types of exercise.

I also have polar chest rate monitor
It is not remotely accurate for the application you're talking about...a HRM isn't going to give you anything remotely accurate worn all day...it will be highly inflated.3 -

If you reread my post, you will see where I said, it's not going to hurt anything to try it, also stating it may not be 100% accurate. My point is that she will get a more accurate picture using a chest strap monitor because it is as close to wearing a EKG machine all day then she would be going off of MFP's calculations or trying to plug the calculations into an excel spreadsheet. Then she can say she tried it and it either worked or it didn't. No harm, no foul. I posted the link because many on here are saying the monitors are not accurate.4

But your link doesn't say they are accurate for what OP is using it for. And when OP is eating thousands more calories than she's actually burning because of this experiment and continues to gain weight and then comes back to ask why and then we have to convince her AGAIN that it isn't accurate - it is a harm and foul.4 -

From the ACC: "The chest strap monitor closely matched readings from the electrocardiogram (EKG), which is the gold standard for measuring the heart's activity (level of agreement with EKG, rc=.996; 1 being perfect agreement);"
We can argue about this all day...is it meant to be worn all day? NO! Can she try it and see? ABSOLUTELY!
She can always go back and re-evaluate. There are a million other users on here that are willing to assist her without getting disgruntled and annoyed. Just scroll along if you're tired of her questions.5 -

Thank you for clarifying this for her! This gives a much better explanation of why she shouldn't wear it all day!2
