Calculadoras de Health & Fitness
BMI, calories, macros and body metrics.
BMI
Calculate your BMI (Body Mass Index), see the WHO classification and the healthy weight range for your height. Switch between metric (kg/cm) and imperial (lb/in).
CalculateHealth & FitnessBMR
Calculate your BMR (basal metabolic rate) with the Mifflin-St Jeor equation — the calories your body burns at rest — and see your daily burn at each activity level.
CalculateHealth & FitnessTDEE
Calculate your TDEE (total daily energy expenditure) from your BMR and activity level, and get the daily calorie target to lose, maintain or gain weight.
CalculateHealth & FitnessSleep
Find the best time to go to bed for your wake-up time. Works backwards in 90-minute sleep cycles so your alarm lands between cycles, not in the middle of deep sleep.
CalculateHealth & FitnessCalorie Deficit
Find the daily calories to lose weight at the rate you choose. The calculator works out your maintenance (TDEE) and the deficit for 0.25 to 1 kg a week.
CalculateHealth & FitnessMacros
Split your daily calories into carbs, protein and fat. Enter your calories and the ratio you want to see how many grams of each macro to eat per day.
CalculateHealth & Fitness1RM
Estimate your one-rep max (1RM) from a weight and the reps you did, using the Epley formula — plus the training loads at each percentage of your 1RM.
CalculateHealth & FitnessIdeal Weight
Find your ideal weight range for your height: the healthy band based on BMI (18.5–24.9) and the ideal weight from the Devine formula. Switch between kg and lb.
CalculateHealth & FitnessBody Fat
Estimate your body fat percentage from height, weight, age and sex using the Deurenberg formula, and see your fat mass and lean mass.
CalculateHealth & FitnessWater Intake
Estimate how much water to drink a day from your body weight and exercise, shown in liters, fluid ounces, cups and glasses.
CalculateHealth & FitnessCalories Burned
Estimate the calories you burn in a workout with the MET method, from the activity, your body weight and how long you exercise.
CalculateHealth & FitnessTarget Heart Rate
Find your maximum heart rate and training zones with the Karvonen method, from your age and resting heart rate.
CalculateHealth & FitnessDaily Protein
Estimate how much protein to eat per day from your body weight and goal, in grams, with a per-meal target and the full range by goal.
CalculateHealth & FitnessFood Calories
Calculate the calories in a food from its grams of carbs, protein, fat and alcohol, using the Atwater factors (4, 4, 9 and 7 kcal per gram).
CalculateHealth & FitnessWaist Circumference
Check the health risk linked to your waist size using the WHO thresholds for men and women. A simple marker of abdominal fat.
CalculateHealth & FitnessWaist-to-Hip
Calculate your waist-to-hip ratio (WHR) and see the health risk category from the WHO thresholds for men and women.
CalculateHealth & FitnessChild BMI
Calculate a child or teen’s BMI from height and weight. For ages 2-19, BMI is read against age-and-sex percentile growth charts, not adult categories.
CalculateHealth & FitnessBMI for Seniors
Calculate BMI for older adults and read it against the higher healthy range (about 23-30) recommended for people aged 65 and over.
CalculateHealth & FitnessLean Body Mass
Estimate your lean body mass — everything that is not fat — from height, weight and sex using the Boer formula, plus your fat mass.
CalculateHealth & FitnessRunning Pace
Find your running pace per mile and per kilometer from a distance and a finish time, plus your speed — and predicted times for the 5K, 10K, half and full marathon.
CalculateHealth & FitnessBlood Alcohol (BAC)
Estimate your blood alcohol content (BAC) from the number of drinks, your weight and the time elapsed, using the Widmark formula. An educational estimate only — never a green light to drive.
