Waist Hip Ratio
Waist Hip Ratio is part of Toolspire and is ready as soon as this page loads. Both measurements must use the same unit. 80 cm over 100 cm is 0.8. The page does not label the ratio healthy or unhealthy.

What you can do here
No cutoff printed
0.8 is the sample arithmetic, not a pass mark.
Same unit required
The detail repeats the two numbers so a mixed unit is yours to notice.
Tape, not a scale
Weight is not an input. BMI is the page that uses weight and height.
The sequence
How to use the Waist Hip Ratio
- 1
Measure both in one unit
80 and 100 are the sample.
- 2
Read 0.8
Eighty divided by one hundred.
- 3
Do not expect a risk label
The page divides. It does not classify you.
Worth knowing
- Waist Hip Ratio on Toolspire: ratio = waist ÷ hip.
- 80 ÷ 100 = 0.8.
- The unit cancels, so centimetres over centimetres and inches over inches match. Mixing them does not.
- A hip of 0 is rejected. There is nothing to divide by.
Two tapes, one quotient
Waist–hip ratio is the waist measurement divided by the hip measurement. Eighty over one hundred is 0.8, whether those were centimetres or inches, as long as both were the same. A waist in centimetres and a hip in inches is a nonsense quotient. The page does not attach a healthy range. Those ranges differ by source and are not a result of the division.
