Calories burned
sewing with a machine
206 kcal / hour Sewing with a machine burns approximately 206 calories per hour for a 70 kg (154 lb) adult, and 103 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 147 to 353 kcal.
It carries a MET value of 2.8 in the 2024 Adult Compendium of Physical Activities.
Calories burned sewing with a machine 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) | 37 | 73 | 110 | 147 | 220 |
| 60 kg (132 lb) | 44 | 88 | 132 | 176 | 265 |
| 70 kg (154 lb) | 51 | 103 | 154 | 206 | 309 |
| 80 kg (176 lb) | 59 | 118 | 176 | 235 | 353 |
| 90 kg (198 lb) | 66 | 132 | 198 | 265 | 397 |
| 100 kg (220 lb) | 73 | 147 | 220 | 294 | 441 |
| 110 kg (243 lb) | 81 | 162 | 243 | 323 | 485 |
| 120 kg (265 lb) | 88 | 176 | 265 | 353 | 529 |

What 206 calories an hour actually means
At MET 2.8, sewing with a machine counts as light activity — it uses about 2.8 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 3 kcal per minute, or 206 kcal across a full hour.
Within home activities, that ranks 33th of 58 activities by energy cost, a little below foraging (MET 2.9) and above walking and carrying small child (MET 2.75).
Put differently: one hour of sewing with a machine costs about the same energy as 42 minutes of ordinary walking.
On the food side, a slice of pizza (about 285 kcal) takes roughly 83 minutes of sewing with a machine 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 sewing with a machine burn per hour?
About 206 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 2.8. A 90 kg adult burns closer to 265 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of sewing with a machine burn?
Roughly 103 kcal at 70 kg, 88 kcal at 60 kg and 147 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of sewing with a machine?
2.8. One MET is the energy you use sitting quietly, so MET 2.8 means 2.8 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.
