To calculate the BSA, multiply the person’s height (**H**) by their weight (**W**), divide the result by 3600, and then take the square root of the outcome. This will give the body surface area in square meters.

The **Body Surface Area (BSA) Calculator** is a valuable tool used in medical fields to estimate the surface area of a person's body based on height and weight. BSA is an essential measurement for calculating drug dosages, particularly in treatments like chemotherapy, and for assessing burn injuries.

The **BSA formula** can vary, with popular methods including the **DuBois** and **Schnur** formulas. This calculator helps determine the **normal body surface area** for adults, children, and even animals. Whether you're looking for **pediatric BSA calculations** or using BSA for drug dosages, this tool provides accurate and reliable results.

### Formula:

$BSA = \sqrt{\frac{H \times W}{3600}}$

Variable | Meaning |
---|---|

BSA |
Body Surface Area (in square meters) |

H |
Height of the person (in centimeters) |

W |
Weight of the person (in kilograms) |

**Solved Calculations :**

**Example 1:**

**Given Values**:

**H**= 170 cm**W**= 70 kg

Calculation | Instructions |
---|---|

BSA = $\sqrt{\frac{170 \times 70}{3600}}$ | Multiply height by weight and divide by 3600. |

BSA = $\sqrt{\frac{11900}{3600}}$ | Simplify the division. |

BSA = $\sqrt{3.31}$ | Take the square root of the result. |

BSA ≈ 1.82 square meters | The result gives the body surface area. |

**Answer**: BSA ≈ 1.82 square meters

**Example 2:**

**Given Values**:

**H**= 160 cm**W**= 60 kg

Calculation | Instructions |
---|---|

BSA = $\sqrt{\frac{160 \times 60}{3600}}$ | Multiply height by weight and divide by 3600. |

BSA = $\sqrt{\frac{9600}{3600}}$ | Simplify the division. |

BSA = $\sqrt{2.67}$ | Take the square root of the result. |

BSA ≈ 1.63 square meters | The result gives the body surface area. |

**Answer**: BSA ≈ 1.63 square meters

**What is Body Surface Area Calculator ?**

Body Surface Area (BSA) is commonly used in clinical settings to calculate medication dosages, particularly for treatments like chemotherapy.

The **BSA formula** is designed to account for the overall surface area of the body rather than just weight or height, making it a more accurate measure for determining dosages. One popular formula is the **DuBois formula**, which is expressed as **BSA = 0.007184 × (weight in kg^0.425) × (height in cm^0.725)**.

For pediatric patients, it helps estimate BSA based on age and weight, ensuring appropriate dosing and treatment plans for young patients. Additionally, it’s often used to calculate **burn surface area**, which is crucial for determining the extent of burns and fluid resuscitation requirements.

In addition to drug dosage calculations, BSA is used in various medical applications, such as evaluating cardiac function, renal function, and overall metabolic rates. For instance, when calculating BSA for chemotherapy, the **BSA calculation formula for chemotherapy** is key to ensuring that the right amount of medication is administered safely.

It provides quick results, helping healthcare providers make informed decisions. It also supports different methods, including the **Schnur formula** and other BSA charts, to help professionals and patients estimate surface areas accurately for treatment or research purposes
