How to Change Height From cm to Feet in a Fitness App

To change height from cm to feet in a fitness app, switch the app's measurement setting first, then confirm that the displayed feet-and-inches value represents the height you already entered. Do not type a converted number into the profile as if it were a new height. The unit changes how the app shows the value. Your height entry is a separate detail.

Use this short check before saving:

Current height entry: __________ cm
Preferred display:    metric / imperial
Expected display:     ______ ft ______ in
Did I change a unit, not my actual height?  yes / no

For example, a profile height of 180 cm displays as about 5 ft 11 in when a fitness app rounds height to whole inches. If an app shows a result you did not expect, stop before editing the height itself. Confirm which setting controls units, then reopen the height field only if your original measurement was actually wrong.

Why does changing the unit look like a height change?

Centimetres and feet-and-inches describe the same length in different forms. The visual change can be surprising because one system uses a single number and the other uses two whole-number parts. That is a display decision, not proof that your profile needs a new measurement.

Keep the two jobs separate:

This distinction is especially useful after moving between gyms, countries, or apps. A new unit preference should not become a reason to invent a more exact height. Use the value you have already chosen, and correct it only when you have a better measurement.

What is the quickest way to check cm against feet and inches?

Use one value, one expected display, and one confirmation. Here is a simple worked check for the 180 cm example:

1. Start with the profile value: 180 cm.
2. Change only the display preference to imperial.
3. Expect the profile to show approximately 5 ft 11 in when rounded to a whole inch.
4. Reopen the profile and make sure you did not replace 180 cm with a number copied from the feet-and-inches display.

The point is not to calculate height by hand every time. It is to spot the common mistake of treating a display conversion as a new profile entry. If the app uses a different rounding rule, follow the number it shows and keep the original measurement only if it remains accurate.

How do fitness apps usually handle metric and imperial settings?

Current workout apps commonly expose a measurement preference because lifters may use kg or lb at different gyms. For example, Hevy's current help centre documents unit changes for exercise logging. (Hevy: change measurement units)

The exact scope differs by app. Some settings affect only workout loads; others also change profile height or distance displays. Before changing anything, check whether the setting applies to the whole profile, a single exercise, or just an active session. That small check prevents a mixed-unit log that is hard to read later.

How do you change height from cm to feet in PeakBFF?

In PeakBFF, open Settings, open your Details, then select the Units row. Choose Imperial to use the app-wide imperial display preference. PeakBFF then presents profile height in feet and inches. Choose Metric to return to centimetres.

This is a signed-in profile setting. The preference controls the app-wide measurement system: metric uses kg, cm, and metric distance displays, while imperial uses lb, feet and inches, and imperial distance displays. Changing the preference keeps the rest of the profile intact. It does not replace the height value with a new measurement.

Use this verified PeakBFF workflow:

1. Write your current height in the check card above.
2. Go to Settings and open Details.
3. Open Units and select Imperial or Metric.
4. Return to the Height row and confirm the display matches your expected unit form.
5. Edit Height only if the measurement itself needs correction. In imperial mode, PeakBFF's height picker uses separate feet and inches wheels; in metric mode, it uses centimetres.

When should you edit the height itself?

Edit the height entry only when the original number is wrong or you have a more reliable measurement. Do not edit it solely because a converted feet and inches display looks unfamiliar. A height field is personal profile data, and the app cannot verify how or when you measured it.

Keep the same careful separation when using that profile information elsewhere in an app. A display setting makes your record easier to read. It is not a clinical measurement, body-composition assessment, or health recommendation.

Bottom line

Change height from cm to feet by changing the measurement preference, then checking the displayed result before editing the actual profile value. In PeakBFF, the app-wide Units setting keeps metric and imperial views consistent, while the Height row remains the place to correct the measurement itself.

Keep height, workout loads, food, and gym sessions in one place with PeakBFF on iOS or Android.
