Calories burned
farming
268 kcal / hour Farming burns approximately 268 calories per hour for a 70 kg (154 lb) adult, and 134 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 192 to 460 kcal.
It carries a MET value of 3.65 in the 2024 Adult Compendium of Physical Activities, which lists 12 measured variations of this activity from MET 1.3 to 7.8.
Calories burned farming by body weight
Energy cost scales with the mass you move, so body weight changes the answer more than anything else.
| Body weight | 15 min | 30 min | 45 min | 60 min | 90 min |
|---|---|---|---|---|---|
| 50 kg (110 lb) | 48 | 96 | 144 | 192 | 287 |
| 60 kg (132 lb) | 57 | 115 | 172 | 230 | 345 |
| 70 kg (154 lb) | 67 | 134 | 201 | 268 | 402 |
| 80 kg (176 lb) | 77 | 153 | 230 | 307 | 460 |
| 90 kg (198 lb) | 86 | 172 | 259 | 345 | 517 |
| 100 kg (220 lb) | 96 | 192 | 287 | 383 | 575 |
| 110 kg (243 lb) | 105 | 211 | 316 | 422 | 632 |

Every official intensity of farming
The Compendium lists 12 separate farming entries, each with its own measured MET value — from 1.3 to 7.8. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.
| Variation | MET | kcal/hr at 70 kg | kcal/hr at 90 kg | Code |
|---|---|---|---|---|
| milking by machine, light effort | 1.3 | 96 | 123 | — |
| light effort, (e.g., cleaning animal sheds, preparing animal feed) | 2 | 147 | 189 | 11246 |
| driving tasks (e.g., driving tractor or harvester) | 2.8 | 206 | 265 | 11248 |
| milking Cows, full milking process, modern milking parlor with milking machines | 3 | 221 | 284 | — |
| feeding small animals | 3.5 | 257 | 331 | 11260 |
| milking by hand, cleaning pails, moderate effort | 3.5 | 257 | 331 | — |
| rice, planting, grain milling activities | 3.8 | 279 | 359 | — |
| feeding cattle, horses | 4.3 | 316 | 406 | 11264 |
| hauling water for animals, fetching water from well or stream | 4.3 | 316 | 406 | 11266 |
| taking care of animals (e.g., grooming, brushing, shearing sheep, assisting with birthing, medical care, branding), general | 4.5 | 331 | 425 | — |
| moderate effort (e.g., feeding animals, chasing cattle by walking and/or horseback, spreading manure, harvesting crops) | 4.8 | 353 | 454 | 11240 |
| vigorous effort (e.g., baling hay, cleaning barn), includes former code 11200 | 7.8 | 573 | 737 | 11220 |
Codes are 2024 Adult Compendium activity codes. A dash means the code could not be read unambiguously from the published table, so it is left blank rather than guessed — the MET value and description are unaffected.
What 268 calories an hour actually means
At MET 3.65, farming counts as moderate activity — it uses about 3.65 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 4 kcal per minute, or 268 kcal across a full hour.
Within occupation, that ranks 35th of 72 activities by energy cost, a little below police officer (MET 3.8) and above lawn keeper (MET 3.5).
Put differently: one hour of farming costs about the same energy as 55 minutes of ordinary walking.
On the food side, a medium banana (about 105 kcal) takes roughly 23 minutes of farming 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 farming burn per hour?
About 268 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 3.65. A 90 kg adult burns closer to 345 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of farming burn?
Roughly 134 kcal at 70 kg, 115 kcal at 60 kg and 192 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of farming?
3.65, taken as the median of the 12 farming entries in the 2024 Adult Compendium, which range from 1.3 to 7.8 depending on intensity. One MET is the energy you use sitting quietly, so MET 3.65 means 3.65 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.
