Estimate your thyroid basal metabolic rate (BMR) using pulse rate and pulse pressure to preliminarily assess hyperthyroidism or hypothyroidism risks.
Enter blood pressure and pulse data.
Gale Formula: BMR% = (Pulse Pressure Difference + Pulse Rate) - 111. This is an empirical formula, for reference screening only, and cannot replace laboratory thyroid function tests.
Fetal Weight Calculator
Estimate fetal weight using ultrasound measurements (BPD, AC, FL) with multiple standard obstetric formulas.
Child Height Predictor Calculator
Predict a child's potential adult height range based on parents' heights and gender, providing parents with a reliable growth trend reference.
BMR Calculator (Basal Metabolic Rate)
Calculate the minimum daily calories your body needs at rest based on gender, height, weight, and age. Get a scientific reference for your diet and fitness plans.
If you suspect you may have a thyroid dysfunction (such as hyperthyroidism or hypothyroidism), this tool can quickly estimate your thyroid basal metabolic rate (BMR) using simple physiological indicators. The thyroid basal metabolic rate refers to the minimum energy expenditure required to maintain basic life activities at rest. The calculation formula combines your pulse rate (beats per minute) and pulse pressure (systolic blood pressure minus diastolic blood pressure) to generate a value and provide a functional status assessment.
What is a normal thyroid metabolic rate?
The normal range is typically ±15%. A calculated result between -10% and +10% is generally considered normal.
Can these results replace a medical examination?
No. This tool only provides a preliminary screening reference. A definitive diagnosis requires laboratory tests such as serum TSH, FT3, and FT4.
You should sit quietly for 15 minutes before measuring. Results will be inaccurate during pregnancy, if you have a fever, or after strenuous exercise. If your calculated results are abnormal, we recommend seeking medical advice as soon as possible.
Typical input example: Pulse rate of 72 bpm + pulse pressure of 38 mmHg ≈ metabolic rate of +5% (Normal). Note that patients with hyperthyroidism often have a pulse rate > 90 bpm accompanied by an increased pulse pressure, while the opposite is true for hypothyroidism. It is recommended to monitor continuously for 3 days and take the average value.
