To calculate the number of calories burned based on your heart rate, weight, and age, multiply the corresponding values with the constants, add them together, subtract a set value, and then multiply by the duration. Finally, divide by 4.184 to get the calories burned.

BPD, or Biparietal Diameter, is a key measurement used in fetal ultrasound to determine the gestational age and monitor fetal growth during pregnancy. It measures the distance between the two sides of the baby’s head.

### Formula :

$\text{Calories Burned} = \frac{((0.6309 \times \text{BPM} + 0.1988 \times \text{Weight} + 0.2017 \times \text{Age} – 55.0969) \times \text{Duration})}{4.184}$

Where:

**BPM**= Beats Per Minute (heart rate)**Weight**= Body weight of the individual (kg)**Age**= Age in years**Duration**= Time spent (minutes)**Calories Burned**= Calories used during the activity

**How to Calculate ?**

**Determine BPM**: Measure your heart rate.**Find Weight**: Enter your body weight.**Input Age**: Use your age.**Duration**: Calculate the time spent in the activity.**Apply Formula**: Insert the values into the formula to get the calories burned.

**Solved Calculations**

**Example 1:**

Variable |
Value |
---|---|

BPM | 140 |

Weight (kg) | 70 |

Age (years) | 30 |

Duration (mins) | 45 |

**Formula**:

$\text{Calories Burned} = \frac{((0.6309 \times 140 + 0.1988 \times 70 + 0.2017 \times 30 – 55.0969) \times 45)}{4.184$**Answer**: 527.9 Calories

**Example 2:**

Variable |
Value |
---|---|

BPM | 120 |

Weight (kg) | 80 |

Age (years) | 25 |

Duration (mins) | 60 |

**Formula**:

$\text{Calories Burned} = \frac{((0.6309 \times 120 + 0.1988 \times 80 + 0.2017 \times 25 – 55.0969) \times 60)}{4.184$**Answer**: 685.4 Calories

**What is Bpd Calculator ?**

The BPD calculator helps measure the biparietal diameter (BPD) of a baby. This measurement helps doctors check the baby’s growth during pregnancy. BPD is the width of the baby’s head, measured from one side to the other.

To use the calculator, you need to input the BPD measurement in millimeters or centimeters. This calculator can tell you if the measurement is normal for the baby’s age. Normal BPD values vary depending on how many weeks pregnant you are.

If the BPD is too high or too low, it can indicate potential health issues. It is important to discuss the results with a doctor. They can provide more information and guidance. Using the BPD calculator is a quick way to get insights about fetal growth. Just enter the numbers and see the results!
