Calories Burned Typing Calculator

Estimate gross calories during typing from body weight, active typing time, and a seated or standing workstation reference, with kcal total and hourly rate.

Estimate gross energy during typing using the seated computer-work reference, 1.3 MET. Gross energy includes resting metabolism. Both posture references use the same population rate.

Typing posture reference

Seated computer work and standing workstation typing both use 1.3 MET in the Adult Compendium. This gives the same estimate for the same weight and time; it does not prove individual energy use is identical.

Body weight

Changing units converts your value. Maximum: 1,000 kg. This is a software limit, not an accuracy range.

Active typing time

Exclude breaks. Zero is valid and gives zero total energy. Changing units converts time. Maximum: 1,440 minutes, a software limit.

Calories Burned Typing Formula

The calculator estimates gross energy during active typing, including resting metabolism. It uses the 2024 Adult Compendium of Physical Activities population references for ages 19–59, not measured personal calories. Both seated computer work (11582) and standing workstation typing (11583) use 1.3 MET.

C = MET \times 3.5 \times BW / 200 \times T

Variables:

C = estimated gross calories during active typing
BW = body weight in kilograms
T = active typing time in minutes, excluding breaks (hours × 60)
MET = the typing posture reference, 1.3 for both seated computer work and standing workstation typing

Pounds convert to kilograms using exactly lb × 0.45359237. Select either posture reference and minutes or hours; changing units converts your value. Both references give the same estimate for equal weight and active time, which does not prove that every individual uses identical energy in both postures.

Typing Calories by Body Weight

Typing is a low-intensity activity. The table shows gross energy estimates at 1.3 MET for either posture reference, using the listed pound weights before rounding to whole kcal. Energy during breaks is excluded.

Body Weight	30 Minutes	60 Minutes	120 Minutes
130 lb	40 kcal	80 kcal	161 kcal
160 lb	50 kcal	99 kcal	198 kcal
190 lb	59 kcal	118 kcal	235 kcal
220 lb	68 kcal	136 kcal	272 kcal

How to Calculate Calories Burned Typing

Enter your body weight and choose pounds or kilograms.
Enter active typing time in minutes or hours, excluding breaks. Zero time is valid and gives zero total typing-period energy.
Choose the seated computer-work or standing workstation typing reference; both use 1.3 MET.
Press Calculate to see estimated gross calories during typing and energy per minute and hour. The reference hourly rate remains defined at zero entered time.

Example

For a person weighing 160 lb and typing for 120 active minutes, either 1.3-MET posture reference gives about 198.13 kcal of gross energy: 1.3 × 3.5 × (160 × 0.45359237) ÷ 200 × 120 ≈ 198.13. The reference hourly rate is about 99.06 kcal/hour. This shared population rate is not a guarantee of identical personal energy use.
