According to Wikipedia,

**Basal Metabolic Rate** is a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining “standard” rates of metabolism for many mammals.

**Basal Metabolic Rate** is the rate of energy expenditure per unit time by endothermic animals at rest.^{} It is reported in energy units per unit time ranging from watt (joule/second) to ml O_{2}/min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food).

Nickzom Calculator is the very first calculator encyclopedia to come out from Nigeria. It is capable of solving over 50,000 calculations and presenting the steps (workings). Fortunately, Nickzom Calculator can solve for your **body metabolic rate**.

You can access Nickzom Calculator via any of these means:

**Web** – https://www.nickzom.org/calculator-plus

**Android (Paid)** – https://play.google.com/store/apps/details?id=org.nickzom.nickzomcalculator

**Android (Free)** – https://play.google.com/store/apps/details?id=com.nickzom.nickzomcalculator

**Apple (Paid)** – https://itunes.apple.com/us/app/nickzom-calculator/id1331162702?mt=8

Once, you have access to Nickzom Calculator proceed to the **Calculator Map, **click on **Health | Fitness Calculator** under **Calculator** section

Then, click on **Basal Metabolic Rate**

Up next, comes a page or activity to enter the values for the respective parameters needed in computing the basal metabolic rate. These parameters according to Nickzom Calculator are:

- Age
- Gender
- Weight (in Kilograms)
- Height (in Centimeters)

**For Example:** I am 23 years old. I am a male. I weight 105 Kilograms and I am 182 centimeters tall.

The screenshot below displays the values entered appropriately.

Now, click on **Calculate**

Therefore, according to Mifflin-St. Joer equation, my basal metabolic rate is **2,077.5 calories per day**.
