How to Use the Sinclair Calculator
The Sinclair Calculator is simple yet powerful, requiring only a few inputs to deliver your adjusted Olympic total. Use competition or recent max values for the most meaningful results. Follow these steps carefully to compute your Sinclair Score accurately.
Select Gender
Choose your gender from the dropdown (Male or Female). This is essential because the Sinclair formula uses separate coefficient curves for men and women, reflecting differences in world record progressions. Selecting the correct gender ensures the calculation fairly represents your relative performance against same-gender elites.
Enter Body Weight (kg)
Input your body weight in kilograms (example: 73 kg). Use your official competition weigh-in or a consistent morning measurement. Bodyweight heavily influences the Sinclair coefficient — lighter lifters receive higher multipliers to reward efficiency. Accuracy here directly affects your final score, so avoid rounding errors.
Enter Total Lifted (kg - Snatch + Clean & Jerk)
Type your combined best snatch and clean & jerk total in kilograms (example: 300 kg). This should come from the same session or meet for validity. The Sinclair system only uses these two Olympic lifts (no squat or bench). Ensure the total reflects lifts performed under standard rules for true comparison.
Select Year for Sinclair Coefficients (Optional)
The field defaults to the current or upcoming coefficient year (2026 in the image). The International Weightlifting Federation (IWF) updates coefficients after each Olympic cycle (every 4 years). Leave it as default unless comparing historical performances. Older years use previous curves, which can slightly alter scores.
Click Calculate Sinclair
Press the blue "Calculate Sinclair" button. The tool instantly applies the selected year's Sinclair formula: Total × Coefficient (based on bodyweight and gender). Your Sinclair Score appears below, along with the benchmark guide (300+ Local → 550+ All-Time Great). Higher scores indicate better pound-for-pound performance. If the result seems unexpected, double-check inputs — especially bodyweight and total. Use this score to gauge your standing against lifters of any size or to predict best-lifter potential in open meets.

FAQs
Did Clive Sinclair invent the pocket calculator?
No Clive Sinclair did not invent the pocket calculator in the strict sense of being the very first. Earlier models existed like the Busicom LE 120A "Handy" from 1971 which fit in a large pocket. However Clive Sinclair launched the Sinclair Executive in 1972 widely recognized as the world's first truly slimline pocket calculator. It measured just 9mm thick easily slipped into a shirt pocket without bulging and became the first mass produced model that popularized the concept. Many sources including obituaries and historical accounts credit him with inventing the modern pocket calculator due to its groundbreaking size design and commercial impact. The Executive's success sparked the pocket calculator boom and earned Sinclair a reputation as the pioneer who made calculators portable and stylish.
How to calculate sinclair score?
To calculate a Sinclair score in Olympic weightlifting add your best snatch and clean & jerk for the total lifted in kilograms. Multiply this total by the Sinclair coefficient which depends on your bodyweight and gender. The coefficient derives from a formula based on world records and updates every Olympic cycle. Input your total bodyweight and gender into an online Sinclair calculator for instant results. The output called the Sinclair total or points estimates what you would lift if competing in the heaviest class at the same ability level. This allows fair comparison across bodyweights. For masters lifters some versions include age adjustments.
Did Sinclair make other calculators?
Yes Sinclair Radionics produced many calculators beyond the famous Executive. After the 1972 Executive models included the Cambridge series starting in 1973 with basic four function versions followed by Memory Programmable and Scientific variants. The Sinclair Scientific in 1974 offered affordable scientific functions. Later came the Oxford series Sovereign and even a Wrist Calculator in 1977. Clive Sinclair's company released over a dozen models through the 1970s ranging from simple arithmetic to programmable and scientific ones. Production stopped around 1979 as focus shifted to computers.
What is the Sinclair measurement?
The Sinclair measurement refers to the Sinclair coefficient or Sinclair total in Olympic weightlifting. It adjusts an athlete's competition total (snatch + clean & jerk) for bodyweight to enable fair comparison across weight classes. The measurement answers: "What would this lifter's total be if they weighed as much as the heaviest class competitor at the same ability level?" Developed by Roy Sinclair (not Clive) it uses statistical data from world records and updates every four years by the International Weightlifting Federation (IWF). Higher Sinclair scores indicate better relative strength.
How to Calculate?
To calculate a Sinclair score sum your best snatch and clean & jerk in kilograms for the total. Find the Sinclair coefficient for your bodyweight and gender from current IWF tables (updated post Olympics). Multiply total by coefficient. Online Sinclair calculators automate this: select gender enter bodyweight (kg) input total (kg) and get the adjusted score instantly. For manual math use the full polynomial formula with gender specific constants. The result normalizes performance for cross class rankings.
What Is Sinclair Coefficient?
The Sinclair coefficient adjusts weightlifting totals for bodyweight in Olympic competitions. It multiplies an athlete's actual total to estimate performance in the heaviest class. Derived statistically from world records separate coefficients exist for males and females. The International Weightlifting Federation recalculates them every Olympic cycle. Lighter lifters get higher coefficients rewarding efficiency. Heavier classes approach 1.0. This enables fair best lifter awards in open meets.
What is Sinclair Coefficient?
The Sinclair coefficient normalizes Olympic weightlifting performances across bodyweights. Multiply it by an athlete's total (snatch + clean & jerk) for the Sinclair total. Based on world record trends it answers how much more (or less) a lifter would total at peak bodyweight with equal ability. Updated every four years by the IWF gender specific versions ensure fairness. It serves as the standard for comparing relative strength in the sport.
With all these variables how do we eliminate them and work out who is the best lifter?
Weightlifting uses the Sinclair coefficient to eliminate variables like bodyweight and determine the best overall lifter. Add snatch and clean & jerk for the total. Multiply by the Sinclair coefficient (based on bodyweight and world records) for an adjusted score. The highest Sinclair total wins best lifter in open competitions regardless of weight class. This statistical method levels the field by estimating equivalent performance in the heaviest category. Gender specific coefficients keep comparisons fair between men and women. The IWF updates it periodically for accuracy.
