Units of measurement

Units of measurement in PregnancyPal are your preferences for weight, height, and temperature — set in /profile/preferences — so the app shows numbers in the system you actually think in.

Everyone reads measurements differently. Some people think in kilograms and Celsius; others in pounds and Fahrenheit. The system you grew up with, or the one your clinic uses, is the one that feels instantly readable — and during pregnancy, when you may be checking your weight or temperature often, that comfort adds up. Rather than forcing one standard, PregnancyPal lets you choose, so logging a number and reading it back feels natural every time.

Set your units once in your preferences and they carry through the places those numbers appear — your tracking screens and your reports. It's a small setting that quietly makes the whole app feel like it speaks your language. And because each measurement is chosen on its own, you're never locked into a single system if you happen to think in pounds for weight but Celsius for temperature.

What you can do with unit settings​

  • Weight — choose kilograms (kg) or pounds (lbs).
  • Height — choose centimeters (cm) or feet (ft).
  • Temperature — choose Celsius (C) or Fahrenheit (F).
  • Apply your choices across tracking screens and reports, so you read one consistent system everywhere.

How to set your units​

  1. Open preferences: go to /profile/preferences.
  2. Set weight units: pick kg or lbs.
  3. Set height units: pick cm or ft.
  4. Set temperature units: pick C or F.
  5. Save — your choices apply going forward.
  6. Check a tracking screen: open weight or temperature tracking to confirm numbers show in your chosen units.

Examples​

  • Metric household — You think in metric, so you set weight to kg, height to cm, and temperature to Celsius. Your weight-tracking chart and Health Report PDF all read in metric.
  • Imperial preference — You're used to pounds and Fahrenheit, so you choose lbs and F. When you log a temperature reading, it's entered and shown the way you're accustomed to.
  • A mixed setup — You prefer pounds for weight but Celsius for temperature. You set weight to lbs and temperature to C independently — each unit is its own choice.
  • Switching to match a new clinic — You move and your new provider uses metric. You open preferences, switch weight to kg and temperature to C, and from then on your tracking screens and reports read in the system your care team uses.

Tips​

  • Set units before you start logging so your history is consistent from day one.
  • Match your provider's system if you'll be sharing numbers — it makes conversations easier.
  • Each unit is independent. Weight, height, and temperature are chosen separately, so mix and match freely.
  • Your reports follow your units. Generate a Health Report PDF and it reflects the units you've set.
  • Changing units changes display, not your readings. Your underlying logged values stay correct; only the way they're presented updates.
  • Temperature units matter for tracking. If you log basal or body temperature, pick C or F to match how you read a thermometer.

Frequently asked questions​

Where do I change my units?​

In your preferences at /profile/preferences. You'll find weight, height, and temperature unit options there.

Which units can I choose?​

Weight in kilograms (kg) or pounds (lbs), height in centimeters (cm) or feet (ft), and temperature in Celsius (C) or Fahrenheit (F).

Do my units apply to reports too?​

Yes. Your chosen units carry through to tracking screens and to your Health Report PDF, so everything reads consistently.

Can I use different systems for different measurements?​

Yes. Each unit is set independently — for example, pounds for weight and Celsius for temperature is perfectly fine.

If I change units, what happens to my existing data?​

Changing units updates how your numbers are displayed. Your logged readings remain accurate; only the presentation changes.

Which units should I pick?​

Whichever you read most naturally, or the system your provider uses if you plan to share your numbers. There's no right answer — it's about comfort.

No. Your trends stay accurate. Switching units re-displays the same readings in a different system, so the shape of your weight or temperature history is unchanged — only the numbers' format updates.

Do units affect anything besides weight, height, and temperature?​

These three settings cover weight, height, and temperature. Other parts of the app, such as appearance and language, are governed by their own separate settings.

What this feature does NOT do​

  • It does not change your actual measurements — it only changes how they're displayed.
  • It does not support unit systems beyond those listed (kg/lbs, cm/ft, C/F).
  • It does not decide what your readings should be or flag them as normal or abnormal. Units are about presentation, not interpretation.
  • It does not automatically match your provider's system — you choose your units yourself.
  • It is not a medical tool. Choosing a unit has no bearing on what any reading means for your health.

PregnancyPal is a personal organizing companion, not medical advice. Unit settings affect display only and do not interpret your measurements. For guidance on what any reading means, contact your healthcare provider directly.
