Estimate gross whole-body energy during seated, light-effort knitting from duration and body weight in lb or kg, including estimated kcal per hour. Gross energy includes resting metabolism; it is not energy used by the hands alone.

Estimate gross energy during seated, light-effort knitting using the documented 1.3-MET activity value. This includes resting energy.

Changing units converts your value. Maximum: 1,500 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.

How the Calculator Works

The calculator multiplies body weight by knitting time and a fixed factor for seated, light-effort knitting at 1.3 MET. Enter weight and duration, then select Calculate to see the session total and estimated kcal per hour. There are no separate knitting-style modes.

The reference covers sitting with light effort. This calculator does not estimate standing, brisk knitting or walking while knitting. Its gross whole-body energy estimate includes resting metabolism and is not a measure of exercise benefit.

Calories Burned Knitting Formula

Use the formula below with the fixed factor for your weight unit. The 2024 Adult Compendium Home Activities table lists seated, light-effort knitting under code 05080 at 1.3 MET. The oxygen-based factor is 1.3 × 3.5 ÷ 200 = 0.02275 kcal/kg/min; exact conversion at 0.45359237 kg/lb gives 0.0103192264175 kcal/lb/min. The Adult Compendium reference population is ages 19–59; individual energy use varies.

Calories = BWlb × Minutes × Factorlb Calories = BWkg × Minutes × Factorkg
  • Calories = estimated gross whole-body energy in kcal
  • BW = body weight
  • Minutes = knitting duration
  • Factor = the fixed seated-light knitting factor in kcal/lb/min or kcal/kg/min

Knitting Factors Used in the Calculator

Supported Activity Factor (kcal/lb/min) Factor (kcal/kg/min) Gross kcal/Hour at 150 lb

Calories Burned Per Hour by Body Weight

The table shows illustrative gross kcal per hour for seated, light-effort knitting at 1.3 MET, rounded to whole kcal. This fixed-reference model scales directly with body weight. For 150 lb and 60 minutes, the unrounded estimate is 92.8730377575 kcal (about 92.87 kcal); the calculator retains unrounded values.

Body Weight Gross kcal/Hour
100 lb 62
120 lb 74
150 lb 93
180 lb 111
200 lb 124
250 lb 155

Session Totals for a 150 lb Person

These illustrative session totals use the seated, light-effort 1.3-MET reference and include resting energy. Values are rounded to whole kcal. Longer time increases the modelled gross total; that total is not a measure of exercise benefit.

Knitting Time Estimated Gross kcal
15 minutes 23
30 minutes 46
60 minutes 93
90 minutes 139
120 minutes 186
180 minutes 279

What Changes Your Calorie Burn?

  • Body weight: the fixed-reference model estimates more gross energy at higher body weight for the same duration.
  • Session length: at the same body weight and fixed reference, the model gives twice the gross energy for 2 hours as for 1 hour.
  • Activity scope: the supported reference is seated, light-effort knitting; standing or walking while knitting is outside this calculator’s model.
  • Individual variation: the reference does not measure personal energy use or adjust for knitting speed, pauses or technique.
  • Gross energy: results include resting metabolism and do not isolate hand movement or establish an exercise benefit.
