Estimate gross whole-body energy while ironing from body weight and duration, using the documented 1.8-MET ironing activity. Gross energy includes resting metabolism and is not a personal measurement.

Estimate gross energy during ironing using the documented 1.8-MET activity value. This includes resting energy.

Changing units converts your value. Maximum: 1,000 lb (453.59237 kg), a software limit rather than an accuracy range.

Enter time spent in this activity. Maximum: 1,440 minutes; this is a software limit. Changing units converts the duration.

Calories Burned Ironing Formula

The calculator uses a single ironing activity at 1.8 MET. It converts body weight to kilograms and uses the oxygen-based factor F = 1.8 × 3.5 ÷ 200 = 0.0315 kcal/kg/min.

C = W × T × F

Variables:

  • C = estimated gross energy in kcal
  • W = body weight in kilograms
  • T = time ironing in minutes
  • F = 0.0315 kcal/kg/min from the fixed 1.8-MET ironing activity

Activity reference: The 2024 Adult Compendium Home Activities table lists ironing at 1.8 MET (code 05070). Its reference population is adults aged 19–59; individual energy use varies. Pounds convert using 0.45359237 kg/lb before calculation.

How Many Calories Does Ironing Burn?

Under the fixed 1.8-MET assumption, estimated gross energy increases with body weight and time spent ironing. The reference value does not measure your session or account for individual differences in energy use; the result is not a food allowance or weight-loss prediction.

125 lb53.6 kcal107.2 kcal
155 lb66.4 kcal132.9 kcal
185 lb79.3 kcal158.6 kcal

The table uses the fixed 1.8-MET activity and exact pounds-to-kilograms conversion. Values are rounded to one decimal; calculations use unrounded values.

How to Calculate Calories Burned Ironing

  1. Enter your body weight and choose pounds or kilograms. The initial unit is pounds; changing units converts your value.
  2. Enter the time spent ironing using the displayed time unit; the initial unit is minutes.
  3. Review the fixed 1.8-MET assumption. Supported upper input limits are 1,000 lb (453.59237 kg) and 1,440 minutes; these are software limits, not an accuracy range.
  4. Select Calculate to see estimated gross energy and the energy rate.

Example

For 155 lb (70.30681735 kg) and 30 minutes of ironing at 1.8 MET:

C ≈ 70.3068 × 30 × 0.0315 ≈ 66.44

Using the unrounded converted weight gives 66.43994239575 kcal, or about 66.44 kcal. This is gross whole-body energy including resting metabolism, not a measurement of an individual session.
