BMI different in Garmin connect to other devices

When I step on my withings scales my BMI comes up as 25.4. yet when I sync with Garmin connect the Garmin connect app says my BMI is 26.1.

The NHS website and other places say my BMI is 25.4 for my weight and height.

Why is Garmin connect sayin my BMI is higher than everywhere else?

And what does a common BMI calculator show as your BMI when you enter the same height and weight? For example this one: https://www.calculator.net/bmi-calculator.html or https://www.calculatorsoup.com/calculators…

Did you enter the correct height in User Settings?

And what does a common BMI calculator show as your BMI when you enter the same height and weight? For example this one: https://www.calculator.net/bmi-calculator.html or https://www.calculatorsoup.com/calculators/health/bmi-calculator.php For me they show the same value as Garmin (rounded to one decimal).

Or you can also use the definition formula for BMI:

BMI = weight ÷ height²

In metric units: BMI = weight (kg) ÷ height² (meters)
In US units: BMI = weight (lb) ÷ height² (inches) * 703

That's the formula Garmin uses too, so If Garmin Connect shows something different, then either the weight, or the height is wrong in your GC User Profile.
