How a Stones and Pounds Weight Loss Calculator Works
A weight loss calculator in stones and pounds takes your starting weight and your current (or goal) weight — both entered in stones and pounds — and gives you the difference in the same units. Because weight is often recorded in kilograms in clinical settings, the calculator also handles the conversion behind the scenes, so you can track progress however your prescriber or pharmacy reports your weight without losing the format that feels intuitive to you.
What the numbers actually tell you
The raw figure — for example, "I have lost 1 stone 4 pounds" — is useful, but it is only one part of the story. Many people on Mounjaro or Wegovy notice that the scale does not move in a straight line: there are weeks of steady progress, occasional plateaus, and weeks where measurements or energy levels change more than weight does. A calculator gives you a snapshot; consistent tracking over time gives you the full picture.
Using stones and pounds alongside other measures
Body weight in any unit is most meaningful when read alongside other data — how clothes fit, energy levels, waist measurements, and how you are feeling day to day. If you would like to explore the same journey using metric figures or a broader calorie context, the weight loss calculator and the calorie and weight loss calculator cover those angles. For a calculator focused purely on stone figures, see the weight loss calculator in stone.
A note on targets
General educational tools can illustrate what different amounts of weight loss look like in stones and pounds, but they cannot set a personal target for you. What is appropriate for your height, health history, and treatment plan is a conversation for your prescriber or doctor — they have the full picture of your individual situation.

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.

Track Your Weight in Stones and Pounds Automatically with GLP Trackr
GLP Trackr's weight tracking feature lets you log your weight in whatever unit you prefer and watch your transformation week by week through visual charts — no manual conversion needed. Every entry builds a running picture of your journey from the day you started, so the progress you might otherwise miss between appointments becomes clearly visible.
The week-at-a-glance and weekly transformation views are particularly useful for anyone whose weight moves in fits and starts, as is common on a GLP-1 programme. Rather than fixating on a single weigh-in, you can see the trend across weeks and understand whether a flat week is a genuine plateau or simply normal variation.
If you want to go deeper, the insights and correlation explorer can surface patterns between your weight log, protein intake, sleep, and other data you record — helping you have more informed conversations with your prescriber about what is working. For setting calorie and protein targets that sit alongside your weight goal, the calorie calculator hub is a good next step.
GLP Trackr is free to try for 7 days and is available on the App Store and Google Play. Start logging your weight in stones and pounds today and let the charts do the maths for you.

The Most Advanced GLP-1 Brain Ever Built.
The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.
Knows Your Cycle
GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

Frequently asked questions.
Subtract your current weight from your starting weight, both in stones and pounds. Convert any remaining pounds over 14 into stones as needed. For example, losing 18 pounds equals 1 stone 4 pounds. A weight loss calculator does this automatically.
Various health organisations offer weight tools using different units. Any reputable calculator converting stones and pounds will use the same maths. For personalised guidance on what weight loss is appropriate for you, speak with your prescriber or doctor.
Results vary considerably between individuals and depend on dose, diet, activity, and other health factors. There is no single typical figure. Your prescriber or doctor is best placed to discuss realistic expectations based on your personal circumstances.
Yes. GLP Trackr lets you log your weight in your preferred unit, including stones and pounds, and displays your progress as visual charts and weekly summaries so you can follow your journey over time.
Plateaus are a commonly reported part of GLP-1 journeys and do not always mean progress has stopped. Log your weight consistently in GLP Trackr to spot trends over time, and discuss any concerns about your progress with your prescriber or doctor.
