Editor In Chief Convert loaded barbell weight from pounds to kilograms for weightlifting and strength training. Enter the total weight in pounds, choose the bar type, and optionally include collar weight and plate tolerance to estimate the exact working weight in kilograms.
Estimate the total loaded weight of one adjustable dumbbell based on the handle, collars, plates per side, and optional fractional plates.
Estimate reps in reserve (RIR) for a set based on reps completed, load used, estimated one-rep max, and set difficulty. This calculator approximates how many additional reps you could have performed before failure.
Calculate the total loaded barbell weight by adding the bar weight, collars, and weight plates on both sides of the bar.
Calculate how much weight to load on each side of a barbell based on total target weight, bar weight, collar weight, and number of sides loaded.
Calculate the total loaded barbell weight for a powerlifting setup using the bar weight and plate quantities loaded per side. This calculator totals both sides and adds the bar for a competition-style lifting setup.
Calculate the weight to load on each side of a barbell based on your target total weight, bar weight, collar weight, and the number of plates per side.
Calculate the total loaded barbell weight based on bar weight and the number of plates loaded on each side. Supports common Olympic plate sizes and returns the full combined weight.
Estimate reps in reserve (RIR) based on the weight used, your estimated one-rep max, reps completed, and exercise type. The calculator uses a standard 1RM-based rep model and adjusts expected reps slightly by exercise category.
Calculate how many weight plates to load on each side of a barbell based on your target total weight, bar weight, available plate size, and whether collars are included.
Estimate training load as a percentage of 1RM using RPE and reps performed. This calculator uses a practical RPE chart-style model to convert the selected repetition count and RPE into an estimated percent of one-rep max.
Estimate one-rep max using RPE, weight lifted, reps performed, exercise type, and training experience. This calculator uses an RPE-adjusted percentage model to convert a submaximal set into an estimated 1RM.
Estimate total weekly training sets for a muscle group based on workouts per week, exercises per workout, sets per exercise, training experience, and goal.
Calculate the value at a specific term in a double progression where each term is formed by multiplying the arithmetic progression factor by the geometric progression factor.
Calculate the value of a term in a linear progression (arithmetic sequence) using the first term, common difference, and target term number. You can also include a starting index when the sequence does not begin at term 1.
Estimate projected body weight after a set number of weeks based on current weight, weekly change, activity goal, and adherence level.
Estimate your next training weight based on your current working weight, completed reps, target reps, training experience, and desired overload rate.
Calculate total workout tonnage by multiplying weight, reps, and sets, with an optional exercise type multiplier to estimate effective training load across different movement patterns.
Calculate total repetitions completed across multiple sets and exercises, with an adjustment for training frequency over a week.
Estimate effective reps in a set based on reps completed, reps in reserve, load as a percentage of 1RM, and exercise type. Effective reps are commonly treated as the final challenging reps performed close to muscular failure, with a small adjustment for lighter loads and exercise stability.
Estimate total hard sets performed for a workout or training week based on exercises, working sets, intensity, and training frequency.
Estimate recommended weekly training sets for a muscle group based on training experience, goal, recovery quality, and weekly training frequency.
Estimate a moderate caffeine dose based on body weight, desired intensity, caffeine sensitivity, and time available for effects. This calculator provides a suggested single-dose amount in milligrams for healthy adults.
Estimate total weekly training volume based on exercises performed, sets per exercise, reps per set, average load, and training frequency. This is useful for tracking resistance training workload across a week.
Estimate total volume load based on item dimensions, quantity, packing efficiency, and load type. Useful for moving, shipping, storage, and freight planning.
Estimate the volume of a rectangular set or stage area in cubic feet using length, width, and height, with adjustments for set complexity and material density.
Calculate total workout training volume based on exercises, sets, reps, and average weight lifted, with an intensity adjustment for bodyweight, light, moderate, or heavy loading.
Estimate a pre-workout caffeine dose in milligrams based on body weight, training intensity, caffeine sensitivity, and whether you recently consumed caffeine. This calculator uses a common performance-oriented approach starting from body-weight-based dosing and adjusts the recommendation for individual tolerance and workout demands.
Estimate total training volume for a workout based on sets, reps, load, exercise count, and intensity. This calculator helps quantify the total amount of work performed in a session.
Estimate a caffeine dose in milligrams based on body weight, unit system, intended use, and personal tolerance. This calculator helps provide a practical caffeine amount using common evidence-based mg per kg ranges.
