Build A Woman Calculator

Health and fitness are important parts of every woman’s life. Whether you want to lose weight, gain muscle, or simply maintain a healthy lifestyle, tracking your BMI (Body Mass Index) and BMR (Basal Metabolic Rate) is essential. That’s why we created the Woman Calculator – a simple online tool designed to calculate BMI and BMR instantly based on your weight, height, and age.

What is the Woman Calculator?

The Woman Calculator is an online BMI and BMR calculator for women. It helps you find:

• BMI (Body Mass Index): An indicator of whether your weight is underweight, normal, overweight, or obese.
• BMR (Basal Metabolic Rate): The number of calories your body needs per day to function at rest.

By entering three simple details — weight, height, and age — you can quickly know your BMI and daily calorie needs.

🔹 How Does It Work?

The calculator uses two formulas:

1. BMI Formula:

BMI=Weight(kg)Height(m)2BMI = \frac{Weight (kg)}{Height (m)^2}BMI=Height(m)2Weight(kg)​

2. BMR Formula (Mifflin-St Jeor Equation for women):

BMR=(10×Weight)+(6.25×Height)−(5×Age)−161BMR = (10 \times Weight) + (6.25 \times Height) - (5 \times Age) - 161BMR=(10×Weight)+(6.25×Height)−(5×Age)−161

Where:

• Weight = kilograms
• Height = centimeters
• Age = years

🔹 How to Use the Woman Calculator

Using the tool is simple:

1. Enter your weight in kilograms.
2. Enter your height in centimeters.
3. Enter your age in years.
4. Click the "Calculate" button.
5. Instantly view your BMI and BMR results.
6. To start again, click "Reset" to clear inputs.

🔹 Example of Calculation

Suppose a woman has:

• Weight: 65 kg
• Height: 165 cm
• Age: 28 years

Step 1 – BMI Calculation: BMI=65(1.65×1.65)=23.88BMI = \frac{65}{(1.65 \times 1.65)} = 23.88BMI=(1.65×1.65)65​=23.88

This BMI falls into the Normal weight range (18.5 – 24.9).

Step 2 – BMR Calculation: BMR=(10×65)+(6.25×165)−(5×28)−161BMR = (10 \times 65) + (6.25 \times 165) - (5 \times 28) - 161BMR=(10×65)+(6.25×165)−(5×28)−161 BMR=650+1031.25−140−161=1380 Calories/dayBMR = 650 + 1031.25 - 140 - 161 = 1380 \, \text{Calories/day}BMR=650+1031.25−140−161=1380Calories/day

So, her body burns around 1380 calories per day at rest.

🔹 Interpreting BMI Results

🔹 Things to Keep in Mind
