Estimate your ideal body weight and adjusted body weight within seconds by using this simple adjusted body weight calculator.

This is a vital calculation that is used in the medical field to estimate the overall health condition of a patient. It helps to estimate the correct dosage of medicines for obese patients.

BMI (Body Mass Index) is widely used to measure obesity in patients as shown in the following table:

Category |
BMI |

Underweight | Below 18.5 kg/m |

Normal | 18.5 to 24.9 kg/m |

Overweight | 25.0 to 29.9 kg/m |

Obese – Class I | 30.0 to 34.9 kg/m |

Obese – Class II | 35.0 to 39.9 kg/m |

Extreme Obesity (Class III) | Above 40 kg/m |

ABW is widely used for overweight or obese patients. It tells about the exact nutritional needs of the patient.

Therefore, it is used when doctors or dietitians have to know the nutritional needs of the body, suggest the dosage of a medicine, or have to create a diet plan for the patient who have gained weight.

Have a look at the following Adjusted Body Weight Equation:

**ABW = IBW + 0.4 (actual weight – IBW)**

**Males Ideal Body Weight: IBW = 50 kg + 2.3 kg for each inch over 5 feet**

**Female Ideal Body Weight: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet**

Where

- IBW represents the ideal body weight
- AW is the actual body weight

In the following table, we have provided the ideal body weight values for both genders.

Height in Feet |
Height in cm |
Average Weight in KG for Male |
Average Weight in KG for Female |

4’6” feet | 137 cm | 28.5 – 34.9 kg | 28.5 – 34.9 kg |

4’7” feet | 140 cm | 30.8 – 38.1 kg | 30.8 – 38.1 kg |

4’8” feet | 142 cm | 33.5 – 40.8 kg | 32.6 – 39.9 kg |

4’9” feet | 145 cm | 35.8 – 43.9 kg | 34.9 – 42.6 kg |

4’10” feet | 147 cm | 38.5 – 46.7 kg | 36.4 – 44.9 kg |

4’11” feet | 150 cm | 40.8 – 49.9 kg | 39 – 47.6 kg |

5’0” feet | 152 cm | 40.1 – 53 kg | 40.8 – 49.9 kg |

5’1” feet | 155 cm | 45.8 – 55.8 kg | 43.1 – 52.6 kg |

5’3” feet | 160 cm | 50.8 – 60.1 kg | 47.2 – 57.6 kg |

5’4” feet | 163 cm | 50.0 – 64.8 kg | 49 – 59.9 kg |

5’5” feet | 165 cm | 55.3 – 68 kg | 51.2 – 62.6 kg |

5’6” feet | 168 cm | 58 – 70.7 kg | 53 – 64.8 kg |

5’7” feet | 170 cm | 60.3 – 73.9 kg | 55.3 – 67.6 kg |

5’8” feet | 173 cm | 63 – 70.6 kg | 57.1 – 69.8 kg |

5’9” feet | 175 cm | 65.3 – 79.8 kg | 59.4 – 72.6 kg |

5’10” feet | 178 cm | 67.6 – 83 kg | 61.2 – 74.8 kg |

5’11” feet | 180 cm | 70.3 – 85.7 kg | 63.5 – 77.5 kg |

6’0” feet | 183 cm | 72.6 – 88.9 kg | 65.3 – 79.8 kg |

Follow the below-mentioned steps to calculate ABW manually:

- First of all, measure your “height” in inches or centimeters
- Determine your “actual weight”
- Find out the “ideal body weight” with the help of the above-written IBW formulas for males and females
- Now put all of these values in the “ABW formula” and get the ABW

If you want to save time, then simply get the help of an online adjusted body weight calculator and perform the whole adjusted body weight calculation swiftly.

Let’s suppose the ideal body weight of a male who is 64 inches tall is 80 Kg. If he is obese (> IBW + 30 %), how to calculate ABW?

Given that:

Actual Body Weight = 80 Kg

Height = 64

Now calculate male IBW:

**IBW = 50 kg + 2.3 kg for each inch over 5 feet**

For finding out the difference = 64 – 60 = 4

IBW = 50 kg + 2.3 x each inch over 60

IBW = 59.2

Now put the values in the ABW Formula:

ABW = IBW + 0.4 (actual weight – IBW)

ABW = 59.2 + 0.4 (80 – 59.2)

ABW = 59.2 + 0.4( 20.8)

ABW = 59.2 + 8.32

ABW = 67.52

The ABW calculator uses the height, actual weight, and gender type to calculate the ideal weight and adjusted weight of the body in various units.

Provides the value of the ABW in kg, pounds(lb), and stones (stone). It represents the nutritional needs of the human body according to the weight and height of a person.

It calculates the IBW according to the gender of a person in kg, pounds(lb), and stones (stone).

This adjusted weight calculator is helpful for doctors and fitness trainers because it enables them to create a good diet plan and dosage of medicine for the patients according to the needs of the body.

Let’s have a look at the following ABW formula for obesity:

AjBW = IBW + 0.4 × (ABW – IBW)

ABW is calculated at the time when there is a need to know the energy requirements of an obese patient. Go for an adjusted bw calculator to perform the correct calculation within seconds.

It happens when you are trying to lose weight, but at the same time, you are gaining muscle. If you are working to lose some weight, then it’s good to use a scale as it will let you measure your progress.
