Formula

This calculator scores walking with the standardized MET equation: a 3.5-MET reference adjusted for effort and conditions, multiplied by body weight and hours.

Calories = METeff x weight (kg) x duration (h)

Alternative Form

Rate (kcal/h) = METeff x weight; Net = (METeff - 1) x weight x hours

Variables

Symbol	Name	Unit	Description
METeff	Effective MET	MET	Reference 3.5 adjusted for effort, grade, speed or stroke
W	Body weight	kg	Current body weight; calories scale linearly
T	Duration	h	Session moving time in hours
C	Calories	kcal	Gross energy including resting baseline
Score	Training score	0-100	Burn (30) + intensity (30) + volume (40)

Explanation

Each component rewards a different healthy behavior: sustained volume, meaningful intensity and total energy expenditure combine into one trackable number.

Derivation

Calories = MET x kg x h (Compendium convention). Score = min(100, min(30, C/500x30) + min(30, MET/10x30) + min(40, hoursx40)).

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Derive the effective MET from the reference value, effort and conditions.

METeff = (base + adjustments) x effort x stroke

Base:3.5

Effort:1x

Intermediate: Base 3.5 adjusted to 3.5

Result: Effective MET = 3.5

Step 2

Convert duration to hours for the MET equation.

Hours = minutes / 60

Minutes:45

Intermediate: 45 / 60

Result: 0.75 hours

Step 3

Apply the MET equation for gross calories.

Calories = METeff x kg x hours

MET:3.5

Weight:70 kg

Intermediate: 3.5 x 70 x 0.75

Result: 184 kcal gross

Step 4

Express the hourly and minute rates.

Rate = METeff x kg

MET:3.5

Intermediate: 3.5 x 70

Result: 245 kcal/h ( 4.1/min)

Step 5

Subtract resting baseline for net calories.

Net = (METeff - 1) x kg x hours

MET:3.5

Intermediate: (3.5 - 1) x 70 x 0.75

Result: 131 kcal above rest

Step 6

Combine burn, intensity and volume into the 0-100 training score.

Score = min(100, burn + intensity + volume)

Burn:11.0/30

Intensity:10.5/30

Volume:30.0/40

Intermediate: burn + intensity + volume components

Result: Training score = 52/100

Final Answer

52/100

Worked Examples

See how the calculator works with different scenarios.

Scenario

A 70 kg person does 45 minutes of walking at moderate effort.

Inputs

Weight:70 kg

Duration:45 min

Effort:moderate

Calculation

MET = 3.5 x 1 = 3.5 Calories = 3.5 x 70 x 0.75 h = 184

Result

184 calories (245/hour)

Interpretation

A solid baseline session. Repeat 3-5x weekly toward the 150-minute guideline.

Understanding Your Result

Your Result: Training Score: 52/100

Typical range: Most sessions score 30-70; 60+ means meaningful volume at honest intensity, and 80+ is a big training day.

What This Means

The training score grades this walking session 0-100 while calories quantify its energy cost.

Why It Matters

Calories link training to nutrition and weight goals; the score links single sessions to weekly consistency, which is what actually builds fitness.

Professional Interpretation

Exercise physiologists prescribe by weekly volume (150+ moderate minutes) rather than single-session burn. This calculator mirrors that: volume is 40 of 100 points.

Where the 40 volume points come from

One full hour earns the maximum 40 volume points; 30 minutes earns 20. Frequency across the week matters more than any single total.

Gross means baseline included

Totals include the ~1 MET resting burn underneath the session. Net above rest runs roughly 29% lower.

Recommendations

•Score under 60: extend duration before raising intensity
•Score 60-79: add one hard interval day weekly
•Big sessions: refuel carbs plus 20-40 g protein
•Re-check weight monthly so totals stay honest
•Pair with strength work twice weekly

Educational Content

Introduction

The Walking translates body weight, time and intensity into calories through the MET system. It is not judgment, just physics: bigger engines and longer sessions burn more fuel.

Concept Explanation

One MET equals sitting quietly. Multiply 3.5 METs by weight in kilograms and by hours to get gross calories. The effort selector scales the reference value from relaxed (0.9x) to hard (1.15x), and the breakdown table shows where the burn accumulates.

Applications

▸Sizing walking sessions sessions to a calorie target

▸Balancing training fuel against weight goals

▸Comparing intensities without a wearable

▸Planning weekly volume across sports

▸Setting honest expectations for fat loss

▸Logging consistent numbers for a training diary

Benefits

•One dashboard for burn rate, totals and training score
•A single 0-100 score to track session quality
•Recommendations generated from your actual numbers
•Interval-level detail showing accumulation
•Instant recalculation for what-if planning

Limitations

•Needs honest weight and duration inputs
•Static average; intervals vary second to second
•Assumes typical technique and conditions
•Does not measure EPOC or adaptation

Best Practices

•Weigh in the morning for consistent inputs
•Log duration including warm-up honestly
•Use hard effort only for truly hard sessions
•Re-run when body weight changes 2+ kg
•Pair with a food log for weight goals

Common Misconceptions

Myth: The number is exact.

Truth: It is a standardized estimate within 20-30% of lab values. Trends across identical inputs matter more than any single total.

Myth: More sweat means more calories.

Truth: Sweat tracks heat and hydration, not energy. Cool dry sessions at the same MET burn the same calories.

Myth: Exercise alone drives fat loss.

Truth: A 300-calorie session is easily eaten back. Combine training with measured nutrition for reliable loss.

Practical Tips

•Weigh in the same conditions each week
•Count warm-up and cool-down in duration
•Reserve hard effort for truly hard sessions
•Compare identical inputs week to week
•Fuel sessions over 75 minutes with carbs
•Strength-train twice weekly alongside cardio

Common Mistakes

Logging wishful durations

Use elapsed moving time from a watch, not gym arrival to departure.

Always selecting hard effort

Most training is moderate; hard should leave you needing recovery tomorrow.

Ignoring body-weight drift

Update weight monthly; a 5 kg change moves totals about 7%.

Eating back every calorie

Eat back half at most when losing weight; estimates skew generous.

Comparing across sports directly

MET scales differ by mechanics; compare within one activity over time.

Chasing single-session records

Weekly totals drive adaptation; one huge session mostly drives soreness.

Assumptions

This calculator makes the following assumptions to provide estimates:

Steady average intensity: The MET value represents the session average, not second-by-second peaks.

Typical mechanics: Assumes normal technique, surfaces and conditions for the activity.

Accurate weight: Body weight input is current and measured, since calories scale linearly with it.

Gross energy: Totals include resting metabolism during the session, per Compendium convention.

Adult physiology: Equations fit typical adults; youth and clinical populations differ.

Limitations

Be aware of these limitations when using this calculator:

No individual calibration: Efficiency varies 10-20% between people at the same MET.

Environment ignored: Heat, altitude, wind and terrain shift real burn versus the estimate.

Afterburn excluded: EPOC adds roughly 6-15% after hard sessions, uncounted here.

Skill effects: Beginners often burn more than skilled athletes at the same pace.

Medical factors: Medication, hormones and body composition alter expenditure.
