Heigth metres converter

The online height converter uses definitions for the units of height as they are established by international treaty in and as defined by the International System of Units SI [1] whose definitions are followed universally around the world.

It is also in accord with the ISO standards for quantities and units [2]. The conversion output is accurate to nine decimal places: more than enough for most applications. There are many possible conversions between the metrics supported in our height converter above.

Some selected examples follow. Below are conversion tables for some of the most used pairs of units of height you can use for quick reference.

Using our height converter above you can construct your own tables for the odd case when you need a quick reference and you do not have access to an internet connection. Our converter also works offline: you can use it as long as the page is cached in your browser.

Other important factors that contribute to a child's adult height include nutrition, health, sports activities, health and age of the mother during pregnancy, etc.

Infants and toddlers grow the fastest. The growth rate declines rapidly from birth to roughly age 2 and declines more slowly thereafter. During puberty, the growth rate increases again to a second maximum, after which it slowly declines to zero. This is typically referred to as the pubertal growth spurt. On average, female and male growth trails off to zero at about 15 and 18 years old, respectively. In some cases, a person's height begins to shrink in middle age, though shrinkage of stature is largely universal in the very elderly.

This is due to factors such as the decreased height of intervertebral discs as well as changes due to degenerative diseases. Many different methods have been developed to predict a child's adult height, some more accurate than others.

Regardless of how accurate the method, height prediction is not an exact science, and it is possible that a child's height can deviate significantly from what is predicted.

Bone age can be used to predict height and is considered more accurate than the other methods listed below. One such method is the Greulich-Pyle method that involves left hand and wrist radiographs to measure bone age. This method compares the radiograph of the patient to that of the nearest standard radiograph in the Greulich-Pyle atlas, a compilation of bone age data. Based on bone age, the height of the child, and the data compiled in the atlas, it is possible to predict height based on the percentage of height growth remaining at a given bone age.

Note that the data in the atlas were obtained between and from Caucasian children, which may limit how accurately the Greulich-Pyle method can be used for current children. The Khamis-Roche method is considered to be one of the more accurate height prediction methods that do not require the measurement of bone age.
