How The MET Method Predicts Hourly Calorie Burn

Every movement has an intensity score called a MET (metabolic equivalent of task). One MET reflects quiet sitting. As effort rises, METs rise. The calorie math uses a simple conversion tied to oxygen use and body mass.

Here’s the core equation most coaches use: calories per minute = MET × 3.5 × body weight (kg) ÷ 200. Multiply by 60 to get an hourly figure. This approach tracks with public health guidance on intensity ranges and the activity codes published in standardized tables used by researchers.

Quick Example You Can Copy

Say you weigh 70 kg and you’re walking briskly at ~4.8 METs. Per minute you’d burn 4.8 × 3.5 × 70 ÷ 200 ≈ 5.88 kcal. Per hour that’s 5.88 × 60 ≈ 353 kcal.

Broad Starter Table: Common Activities

This first table lists typical METs with an hour estimate for a 70 kg person. Use it to scan where your routine lands on the intensity ladder.

Activity (Typical Pace)	MET	Calories/Hour (70 kg)
Sitting Quietly	1.0	~70
Standing Desk Work	1.8	~126
Easy Walk (~3.0 mph)	3.3	~277
Brisk Walk (~4.0 mph)	5.0	~367
Hiking (Moderate Grade)	6.0	~441
Running (6.0 mph)	9.8	~720
Cycling (12–13.9 mph)	8.0	~588
Rowing Machine (Moderate)	7.0	~514
Strength Training (Circuit)	6.0	~441
Yoga (Hatha)	2.5	~210
House Cleaning (Vigorous)	3.5	~308
Yard Work (Mowing, Walk)	5.5	~404

METs are standardized so a 4 MET task uses four times the energy of quiet sitting. Once you dial in your daily plan, setting your daily calorie needs gets easier because you’re plugging realistic burn numbers into your weekly routine.

Calories Burned Per Hour Calculator Method — MET Formula In Plain English

Start with your body weight in kilograms. If you have pounds, divide by 2.2046 to convert. Pick a MET that matches your pace or task. Plug both into the equation, then multiply by 60 for an hourly estimate.

Step-By-Step

1. Find the activity MET from a trusted table.
2. Convert your weight to kilograms.
3. Compute calories per minute with the formula.
4. Multiply by session minutes for a total, or by 60 for an hourly number.

Where To Get Reliable MET Numbers

Public health resources outline intensity bands and provide references to large activity lists. You’ll see moderate work around 3–5.9 METs and vigorous work at 6.0+ METs, with hundreds of coded activities cataloged in researcher-maintained tables. Link out to those primary sources when you want deeper lookups.

What Changes The Hourly Burn

Pace and grade: Faster movement or uphill terrain spikes METs. A shift from a flat walk to a steady climb can jump a full point or more.

Body mass: The formula scales with kilograms, so two people at the same pace won’t burn the same number per minute.

Efficiency: Experience, technique, and equipment (like a stiff-soled shoe on the bike) can nudge real-world costs up or down compared with the table value.

Heat and load: High temperature, pack weight, and stop-and-go patterns move the needle. If your day includes stairs, sand, or wind, expect higher output than the base line.

Worked Examples With Different Weights

Use these quick calculations to sanity-check your own estimate. Each row shows the same activity scaled across body weights.

Scenario	Weight & MET	Calories/Hour
Brisk Walk (~4.0 mph)	60 kg @ 5.0 MET	~315
Brisk Walk (~4.0 mph)	75 kg @ 5.0 MET	~394
Brisk Walk (~4.0 mph)	90 kg @ 5.0 MET	~473
Running (6.0 mph)	60 kg @ 9.8 MET	~617
Running (6.0 mph)	75 kg @ 9.8 MET	~771
Running (6.0 mph)	90 kg @ 9.8 MET	~926
Indoor Row (Moderate)	60 kg @ 7.0 MET	~441
Indoor Row (Moderate)	75 kg @ 7.0 MET	~551
Indoor Row (Moderate)	90 kg @ 7.0 MET	~662

How To Pick The Right MET For Your Pace

Walking: Leisure strolls sit near 2–3.5 METs; brisk urban walking climbs to ~5.0; fast hiking with a pack pushes higher.

Running: Easy jogging lives near 7–8 METs; steady 10-minute miles reach ~9.8; faster paces go well into double digits.

Cycling: Easy spins hover at 4–6 METs; a steady commute at 12–13.9 mph averages ~8.0; climbs and sprints exceed that.

Daily tasks: Vigorous cleaning and yard work often land in the 3–6 MET range and add up over an hour.

Pro Tip: Match METs To Descriptions, Not Labels

Speed, incline, and resistance matter more than the app name. If your treadmill says “fat burn” but you’re breathing hard, you’re likely in a higher MET band than the preset suggests.

Turn Estimates Into Action

Pick one movement you enjoy, set a time target, and track pace with a watch or phone. A steady plan beats sporadic surges. When you’re ready to fine-tune, pair estimates with your step counts, bike power, or heart-rate zones for tighter ranges. If you want a daily baseline to weigh against these workouts, use your typical routine and step count to ballpark a full-day burn, then adjust food and workouts against that pattern over a couple of weeks.

Safety And Sanity Checks

• If you’re new to activity, start in the moderate band and build.
• Hold good form. Sloppy reps cost energy but not in the way you want.
• Fuel and hydrate for sessions over an hour so pace stays even.

FAQs You’re Probably Thinking (Answered Inline)

Do Wearables Replace The Formula?

Not exactly. Wrist units estimate from motion and heart rate. The MET equation estimates from intensity tables and body mass. When both agree within a small range across a week, your number is probably close enough for planning.

What If My Pace Fluctuates?

Break a session into chunks. Ten minutes easy, twenty steady, ten hard? Calculate each segment with its MET, then add the totals. The arithmetic stays simple.

Can I Use Pounds?

Yes. Convert pounds to kilograms first by dividing by 2.2046. Small rounding differences won’t change planning decisions for most people.

Credible References For Your Deep Dives

Intensity bands and the idea of METs come from long-standing public health material. Standardized activity codes list hundreds of tasks with MET values used in research and fitness practice. You can skim official guidance on measuring intensity and browse MET tables to pick the closest match to your pace. For quick cardio planning, the ranges above keep you in the right ballpark.

Build A Routine You Can Repeat

Pick two steady days and one slightly harder day this week. Lock those into your calendar. If steps are your anchor, a short primer on tracking methods can help you set a realistic movement floor when life gets busy. When you’re ready to map food intake to your output, you’ll have a clean activity baseline to work from.
