How Many Calories Does Your Activity Actually Burn?
Calorie burn estimates come from MET values — Metabolic Equivalent of Task — a ratio of exercise intensity to resting metabolic rate. MET 1.0 equals resting. MET 3.5 means burning 3.5 times resting calories. The formula is: Calories = MET × Weight (kg) × Hours. A 155-lb (70 kg) person exercising for 1 hour at MET 3.5 burns approximately 245 calories. These calculators apply that formula with activity-specific MET values and body weight to produce personalized estimates.
Walking and Hiking
Walking at 3.5 mph has a MET of approximately 3.5 — a 155-lb person burns about 245 calories per hour. The Walking Calorie Calculator adjusts for pace, as faster walking (4.5 mph) reaches MET 5.0 and burns about 350 calories per hour. Hiking with a loaded pack is significantly more demanding: MET values of 6.0-8.5 depending on terrain and pack weight. The Hiking Calorie Calculator adds elevation gain as a multiplier — ascending 1,000 feet per hour adds approximately 200-250 calories over flat-terrain estimates at the same distance.
High-Intensity Activities
Jump rope is one of the highest-calorie activities per minute available without equipment. At moderate pace (average speed), MET reaches 10.0-12.3 — a 155-lb person burns approximately 700-850 calories per hour. The Jump Rope Calorie Calculator accounts for jump speed and duration. Compare: walking burns ~245 cal/hour, cycling at leisure burns ~422 cal/hour, jump rope burns ~744 cal/hour. For a 30-minute session, jump rope approximately triples the calorie burn of a 30-minute walk at the same duration.
Mind-Body Activities
Yoga calorie burn varies dramatically by style. Restorative yoga has a MET of approximately 2.0-2.5, barely above resting, burning about 140-175 calories per hour for a 155-lb person. Power yoga and vinyasa reach MET 4.0-5.0, burning 280-350 calories per hour. Hot yoga adds cardiovascular demand from heat stress. The Yoga Calorie Calculator distinguishes between styles to give accurate estimates rather than averaging across all yoga types.
Sports and Climbing
The Climbing Grade Converter maps grades between systems (V-scale, Fontainebleau, YDS, French) for climbers competing internationally or following training programs from different countries. The Pickleball Scoring Calculator and Padel Scoring Calculator track match scores with the correct serving rotation rules for each sport, which differ significantly from standard tennis scoring.
Frequently Asked Questions
How many calories does walking 10,000 steps burn?
Walking 10,000 steps covers approximately 4-5 miles depending on stride length. At a moderate pace (3.0-3.5 mph), a 155-lb person burns approximately 300-400 calories for 10,000 steps. The exact number varies with bodyweight (heavier people burn more), pace (faster burns more per hour but the same distance at any speed burns similar calories), and terrain (hills add significantly). The Walking Calorie Calculator provides a personalized estimate based on your weight and pace.
Which exercise burns the most calories per minute?
Among accessible activities, vigorous jump rope (10+ mph, double-unders) tops most lists at MET 12-14, burning 14-17 calories per minute for a 155-lb person. Other high-burn activities include rowing (MET 8-12), running at 8 mph+ (MET 11-13), and swimming butterfly stroke (MET 14). Climbing stairs vigorously reaches MET 15. The key variable is sustained intensity — most people can't maintain maximum jump rope intensity for more than 2-3 minutes, making 30-minute moderate hiking or cycling more practical for total calorie burn.
How accurate are MET-based calorie burn calculators?
MET-based estimates are accurate within ±15-20% for most activities under standard conditions. The main sources of error are individual metabolic variation (some people have higher or lower resting metabolic rates), fitness level (fit athletes burn fewer calories at the same absolute intensity), and activity conditions (heat, hills, pack weight). These calculators give a reliable estimate for planning and tracking progress — more accurate than generic watch estimates, which use heart rate as a proxy and often err by 20-30%.
Does yoga actually burn significant calories?
It depends entirely on the style. Restorative and yin yoga burn approximately the same as a slow walk — 100-150 calories per 45-minute session for a 155-lb person. Power yoga and heated vinyasa can reach 300-400 calories per 60-minute session, comparable to moderate cycling. Hot yoga adds approximately 10-15% to estimates from heat stress. If calorie burn is the goal, vigorous yoga styles (power, Ashtanga, Baptiste) compare favorably with moderate cardio. Gentler styles provide flexibility and stress-reduction benefits, not significant calorie expenditure.
