# BMR Calculator

## Basal Metabolic Rate (BMR) Calculator

### Basal Metabolic Rate:

#### Harris-Benedict Formula

##### For Men:

BMR = 88.362 + (13.397 x weight in kg) + 4.799 x height in cm) - (5.677 x age in years)

##### For Women:

BMR = 655 + (9.6 x weight in kg) + (1.8 x height in cm) - (4.7 x age in years)

### How to Use the BMR Calculator?

The BMR calculator is very simple to use.

Here's a step-by-step guide on how to use a BMR calculator and an example calculation:

Step 01: Input Gender: Select your gender (male or female).

Step 02: Enter Age: Input your age in years.

Step 03: Enter Weight: Input your weight in kilograms (kg).

Step 04: Enter Height: Input your height in centimeters (cm).

Different formulas are used to calculate BMR based on gender. The most common formulas are:

Our BMR calculator works with the most accurate BMR calculation equation, the Harris-Benedict equation, which is used for both males and females.

#### Example

Let's suppose a user came to calculate her BMR. She puts the following details:

• Gender: Female
• Age: 30 years
• Weight: 60 kg
• Height: 165 cm

#### Solution

The calculator implements the equation in this way:

BMR = 655 + (9.6 x weight in kg) + (1.8 x height in cm) - (4.7 x age in years)

Weight Component: 9.6 x 60 = 576

Height Component: 1.8 x 165 = 297

Age Component: 4.7 x 30 = 141

Combining the above:

BMR = 655 + 576 + 297 - 141

BMR = 1387

So, the BMR for a 30-year-old female with a weight of 60 kg and height of 165 cm is 1387 calories per day.

### Who Uses a BMR Calculator?
