Calories burned at rest

Type weight, minutes, and a low MET. 70 kg, 60 min and 1.3 give 91. 80 kg, 120 min and 1 give 160. 60 kg, 90 min and 1.5 give 135. This is MET × mass × time, not Mifflin.

Not a clinic verdict. The main result is rounded kcal from MET. BMR shows only after height, age, sex, and activity.

How it works

Calories burned at rest in this calculator is MET times weight in kg times minutes over 60. 1.3 × 70 × (60/60) = 91. The calculator writes 91, a bare rounded number. 1 × 80 × 2 = 160. 1.5 × 60 × 1.5 = 135.

The MET list is 1, 1.3, 1.5, and 1.8. Default 1.3 is sitting. 1 is lying. This is not Mifflin. BMR computes a base from weight, height, age, and sex, with no session minutes.

The kcal-per-minute, BMR, and TDEE rows are extras. 91 does not wait for height. Without a profile you still get 91. The TDEE percent stays hidden too.

Daily TDEE lives on the TDEE card. The resting base without movement lives on BMR. Here a time slice at a low MET, for example an hour of sitting at 70 kg.

Type weight, type minutes, pick MET, then Calculate. Zero minutes leaves a blank. A comma in 70.5 parses. A sketch, not a calorimeter reading and not a doctor order.

70 kg, 60 min and 1.3 MET give 91. 80 kg, 120 min and 1 MET give 160. 60 kg, 90 min and 1.5 MET give 135. With a US header, weight is pounds. Resting burn starts from mass in kg.

Formula

kcal = MET × kg × (min / 60)

How to use

  1. Type weight, minutes and MET, for example 70 kg, 60 min and 1.3.
  2. Type minutes, for example 60, and pick 1.3 MET.
  3. Click Calculate. The result is 91.
  4. 80 kg, 120 min and 1 MET give 160. 60 kg, 90 min and 1.5 give 135.
  5. Mifflin BMR lives on the BMR page. Here only a low MET × mass × time.

70 kg, 60 min and 1.3 MET = 91

kcal = MET × kg × (min/60). 70, 60 and 1.3 give 91. This is not Mifflin BMR.

rest
A low MET times mass times time. 70 kg and 60 min at 1.3 show 91.
MET
Intensity from the list. 1 is lying and 160 at 80 kg and 120 min. 1.5 at 60 kg and 90 min gives 135.
mass
Weight in kg. 70 kg at 1.3 and 60 min is 91. BMR from that mass lives on BMR.

Examples

Example 1

  • 70 kg
  • 60 min

160

How many kcal at 80 kg, 120 min and 1 MET? 160.

Example 3

  • 60 kg
  • 90 min
  • 1.5 MET

135

Common questions

How many kcal at 70 kg, 60 min and 1.3 MET?

91. 1.3 × 70 × 1, then rounding. A bare number.

What about 80 kg, 120 min and 1 MET?

160. 1 × 80 × 2.

What about 60 kg, 90 min and 1.5 MET?

135. 1.5 × 60 × 1.5.

Is this BMR?

No. The Mifflin–St Jeor formula computes BMR from weight, height, age, and sex. Here the result is MET × body mass × time in hours.

Where does 1.3 MET come from?

The default sitting option on the list. There are also 1, 1.5, and 1.8.

Is 91 a lab reading?

No. A sketch from a product. Not a clinic verdict.

When does BMR show in this calculator?

After height, age, sex, and activity. 91 alone does not need them.

What if minutes are 0?

A blank. Time and weight must be positive.

Does a comma in 70.5 work?

Yes. 1.3 × 70.5 × 1 rounds to 92.

Knowledge sources

Rest multiplies MET, mass and minutes. BMR shows only after the extra fields.
