How a Stone-Based Weight Loss Calculator Works
A weight loss calculator in stone takes three inputs — your starting weight, your current weight, and an optional goal weight — and works out how much you have lost and how much remains. Because one stone equals 14 pounds (approximately 6.35 kg), the conversion can feel more meaningful than tracking in pounds or kilograms alone for people accustomed to thinking in stone.
What the numbers actually tell you
The calculator typically shows:
- Weight lost so far — expressed in stone and pounds (for example, 1 st 4 lb)
- Percentage of body weight lost — a useful complement to the raw figure, since progress looks different at different starting weights
- Remaining to goal — how far you are from a target weight you have set with your prescriber or doctor
It is worth remembering that no calculator can predict how quickly you will reach a goal. Progress on a GLP-1 medicine varies considerably from person to person and is shaped by dose, diet, activity, sleep, and many individual factors. A calculator gives you a snapshot — not a guarantee or a clinical forecast.
Using it alongside other measures
Weight in stone is one useful data point, but many people on Mounjaro or Wegovy find their body composition changes in ways the scale does not fully capture. Combining stone-based weight tracking with measurements, energy levels, and how clothes fit gives a rounder picture of progress. You can explore a general weight loss calculator for a broader view, or use a calories and weight loss calculator to understand the energy side of the equation alongside the stone-by-stone progress. For a fuller calorie-based perspective, a calorie and weight loss calculator can also be useful. If you prefer to see all your figures in stones and pounds throughout, the weight loss calculator in stones and pounds keeps everything in the same unit.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.

Tracking Your Weight in Stone Automatically with GLP Trackr
Manually converting weights and recalculating your progress every week adds friction to a routine that is already demanding. GLP Trackr's weight and body tracking feature logs your weight each day and builds a visual chart of your journey over time — so the trend is always visible without any arithmetic on your part.
See your transformation week by week
The daily morning check-in takes about 30 seconds: log your weight, mood, energy, and a few other markers, and GLP Trackr turns that data into a week-at-a-glance view and longer-term progress charts. Over weeks and months, patterns emerge — including plateaus — that can be genuinely useful to discuss with your prescriber or doctor at your next appointment.
Insights that go beyond the number
The app's insights and analytics layer surfaces correlations in your own data: how sleep, protein intake, or hydration relate to the movement (or stillness) of your weight. This is not a clinical prediction — it is a personal-data lens that helps you understand your own journey more clearly. For the full calorie and macro picture that feeds into your weight results, the calorie tracking hub covers everything from food logging to daily targets.
If you notice your weight has stalled and want to understand the context — your dose history, recent food intake, step count — having that data already logged means you arrive at any conversation with your healthcare team well prepared rather than trying to recall weeks from memory.

Frequently asked questions.
Subtract your current weight from your starting weight and convert the result: divide the total pounds by 14 to get stone, with the remainder as pounds. For example, losing 18 lb equals 1 stone 4 lb. A weight loss calculator in stone does this automatically.
One stone equals exactly 14 pounds, or approximately 6.35 kilograms. This fixed conversion is used whenever a stone-based calculator works out how much weight you have lost or how far you are from a goal.
Both figures are useful. Percentage of body weight lost allows comparison across different starting weights, while stone and pounds often feel more tangible day to day. Many people find tracking both together gives the clearest picture of progress on a GLP-1 medicine.
Progress varies considerably between individuals and depends on dose, diet, activity, and other personal factors. No calculator can predict your result. Your prescriber or doctor is best placed to discuss realistic expectations based on your own health history.
Yes. GLP Trackr's weight logging and progress charts record your weigh-ins over time, building a visual trend so you can see how your journey is progressing without manual conversions. The app is free to try for 7 days on iOS and Android.
