Calories burned
ironing
132 kcal / hour Ironing burns approximately 132 calories per hour for a 70 kg (154 lb) adult, and 66 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 95 to 227 kcal.
It carries a MET value of 1.8 in the 2024 Adult Compendium of Physical Activities.
Calories burned ironing 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) | 24 | 47 | 71 | 95 | 142 |
| 60 kg (132 lb) | 28 | 57 | 85 | 113 | 170 |
| 70 kg (154 lb) | 33 | 66 | 99 | 132 | 198 |
| 80 kg (176 lb) | 38 | 76 | 113 | 151 | 227 |
| 90 kg (198 lb) | 43 | 85 | 128 | 170 | 255 |
| 100 kg (220 lb) | 47 | 95 | 142 | 189 | 284 |
| 110 kg (243 lb) | 52 | 104 | 156 | 208 | 312 |
| 120 kg (265 lb) | 57 | 113 | 170 | 227 | 340 |

What 132 calories an hour actually means
At MET 1.8, ironing counts as light activity — it uses about 1.8 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 2 kcal per minute, or 132 kcal across a full hour.
Within home activities, that ranks 55th of 58 activities by energy cost, a little below watering plants (MET 2) and above standing in boat (MET 1.5).
Put differently: one hour of ironing costs about the same energy as 27 minutes of ordinary walking.
On the food side, a can of cola (about 140 kcal) takes roughly 63 minutes of ironing 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 ironing burn per hour?
About 132 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 1.8. A 90 kg adult burns closer to 170 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of ironing burn?
Roughly 66 kcal at 70 kg, 57 kcal at 60 kg and 95 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of ironing?
1.8. One MET is the energy you use sitting quietly, so MET 1.8 means 1.8 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.
