Calculate with code

These short examples use the same inputs and core calculation as this tool. Adapt validation and formatting to your application.

JavaScript

const weightKg = 70, heightCm = 175, age = 30;
const bmr = 10*weightKg + 6.25*heightCm - 5*age + 5;
console.log(bmr); // Mifflin-St Jeor example, activity multiplier applied separately

TypeScript

const weightKg=70, heightCm=175, age=30;
const bmr: number = 10*weightKg + 6.25*heightCm - 5*age + 5;
console.log(bmr); // 1668.75 kcal/day before activity factor

Python

weight, height, age = 70, 175, 30
print(10*weight + 6.25*height - 5*age + 5)  # 1668.75 kcal/day BMR estimate

Java

double bmr = 10*70 + 6.25*175 - 5*30 + 5;
System.out.println(bmr); // 1668.75 kcal/day BMR estimate

double bmr = 10*70 + 6.25*175 - 5*30 + 5;
Console.WriteLine(bmr); // 1668.75 kcal/day BMR estimate
