What 279 calories an hour actually means
At MET 3.8, hiking slowly or ambling through fields and… counts as moderate activity — it uses about 3.8 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 5 kcal per minute, or 279 kcal across a full hour.
Within walking, that ranks 17th of 28 activities by energy cost, a little below carrying 5 to 14 lb load (MET 4) and above descending stairs (MET 3.5).
Put differently: one hour of hiking slowly or ambling through fields and… costs about the same energy as 57 minutes of ordinary walking.
On the food side, a chocolate bar (about 235 kcal) takes roughly 50 minutes of hiking slowly or ambling through fields and… to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.
Questions
How many calories does hiking slowly or ambling through fields and… burn per hour?
About 279 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 3.8. A 90 kg adult burns closer to 359 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of hiking slowly or ambling through fields and… burn?
Roughly 140 kcal at 70 kg, 120 kcal at 60 kg and 200 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of hiking slowly or ambling through fields and…?
3.8. One MET is the energy you use sitting quietly, so MET 3.8 means 3.8 times that rate.
Is this an exact number of calories?
No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.
