Bmi Heart Rate Calculator

BMI and Heart Rate Calculator

This calculator helps you understand your Body Mass Index (BMI) and how it relates to your resting heart rate. BMI is a measure of body fat based on height and weight. Resting heart rate is the number of times your heart beats per minute when you are at rest. A healthy resting heart rate typically falls between 60 and 100 beats per minute for adults, though it can vary based on fitness level and other factors.

function calculateBMIAndHeartRate() { var weight = parseFloat(document.getElementById("weight").value); var height = parseFloat(document.getElementById("height").value); var age = parseInt(document.getElementById("age").value); var restingHeartRate = parseInt(document.getElementById("restingHeartRate").value); var resultDiv = document.getElementById("result"); resultDiv.innerHTML = ""; // Clear previous results if (isNaN(weight) || isNaN(height) || isNaN(age) || isNaN(restingHeartRate) || weight <= 0 || height <= 0 || age <= 0 || restingHeartRate <= 0) { resultDiv.innerHTML = "Please enter valid positive numbers for all fields."; return; } // BMI Calculation var heightInMeters = height / 100; var bmi = weight / (heightInMeters * heightInMeters); bmi = bmi.toFixed(2); var bmiCategory = ""; if (bmi = 18.5 && bmi = 25 && bmi < 29.9) { bmiCategory = "Overweight"; } else { bmiCategory = "Obese"; } // Heart Rate Interpretation (simplified general guidelines) var heartRateCategory = ""; if (restingHeartRate = 60 && restingHeartRate <= 100) { heartRateCategory = "Within the normal range"; } else { heartRateCategory = "Higher than average (could indicate stress, illness, or deconditioning – consult a doctor)"; } var bmiAndHeartRateInfo = "
