Formula

This calculator prices each kilometer of walking at reference pace (12.43 min), then scales by weight and distance.

Per-km = MET x weight (kg) x reference-pace hours

Alternative Form

Total = per-unit x distance; Time = distance x reference pace

Variables

Symbol	Name	Unit	Description
MET	Reference MET	MET	Compendium value 3.5
W	Weight	kg	Body weight
u	Per-unit cost	kcal	MET x kg x pace-hours
d	Distance	km	Trip distance
C	Total	kcal	Per-unit times distance
Score	Session score	0-100	Burn, intensity and volume

Explanation

Per-unit pricing separates efficiency (cost per kilometer) from volume (how many km).

Derivation

u = 3.5 x W x 0.2072 h. Score mirrors the calorie calculator.

Step-by-Step Calculation

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

Step 1

Price one kilometer at reference pace.

Per-km = MET x kg x pace-hours

MET:3.5

Pace:12.43 min

Intermediate: 3.5 x 70 x 0.207

Result: 51 kcal per kilometer

Step 2

Convert to the other unit.

Per-mile = per-km x 1.609344

PerUnit:51 kcal

Intermediate: unit conversion

Result: 82 kcal per mile

Step 3

Multiply by trip distance.

Total = per-unit x distance

Distance:5 km

Intermediate: 51 x 5

Result: 254 kcal

Step 4

Estimate moving time at reference pace.

Time = distance x pace

Distance:5 km

Intermediate: 5 x 12.43 min

Result: 1:02:09

Step 5

Split the trip into thirds.

Third = total / 3

Total:254 kcal

Intermediate: 254 / 3

Result: 85 kcal per third

Step 6

Score burn, intensity and volume 0-100.

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

Total:254 kcal

Intermediate: burn + intensity + volume

Result: Session score = 66/100

Final Answer

66/100

Worked Examples

See how the calculator works with different scenarios.

Scenario

A 70 kg person covers 5 km.

Inputs

Weight:70 kg

Distance:5 km

Calculation

Per-km = 3.5 x 70 x 0.207 = 51; Total = 51 x 5 = 254

Result

254 kcal

Interpretation

The reference per-kilometer cost for this activity.

Understanding Your Result

Your Result: Session Score: 66/100

Typical range: Near 51 kcal per kilometer at 70 kg is typical; totals over 300 kcal deserve refueling.

What This Means

The per-kilometer figure is the energy toll of one kilometer; the total scales it to your trip.

Why It Matters

Unit pricing compares routes, tracks efficiency gains and sizes fueling precisely.

Professional Interpretation

Falling per-unit cost at fixed pace signals improving economy — a key endurance adaptation.

Pace assumption

Reference pace is 12.43 min per kilometer; faster efforts cost slightly less per unit through momentum but more per minute.

Weight scaling

Every kilogram adds the same increment per kilometer, so totals stay honest as weight changes.

Recommendations

•Compare identical routes over time
•Fuel totals over 300 kcal
•Allow fluids past the hour
•Scale by current weight
•Log per-unit trends

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 trips 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.

Glossary

Technical terms used in mortgage calculations explained in plain language.

MET: Metabolic Equivalent of Task; 1 MET is resting energy use, and walking uses a multiple of it.
Gross calories: Total energy used including the resting metabolism underneath the activity.
Net calories: Extra energy above rest; gross minus roughly 1 MET of baseline.
Compendium: The Compendium of Physical Activities, the standard MET reference researchers use.
EPOC: Afterburn: slightly elevated metabolism after hard sessions, typically 6-15% extra.
RPE: Rating of perceived exertion, a 1-10 scale of how hard the effort feels.
Zone 2: Easy aerobic intensity where conversation stays comfortable; the base of endurance.
Threshold: The hardest intensity sustainable near one hour; interval training targets it.
TDEE: Total daily energy expenditure: BMR plus activity plus food thermogenesis.
BMR: Basal metabolic rate: resting calorie need for vital functions.
Thermic effect: Calories used digesting food, roughly 10% of intake.
Training load: Volume times intensity across sessions; manages fitness against fatigue.
