One thousand calories in the meter band means: one thousand calories (qi ā NK m) is also called a thousand calories. A unit of heat, equal to 1000 calories, i.e. 1 kg of water to raise its temperature 1 degree Celsius (symbol is kilocalories).

Conversion unit: 1 kcal = 1 kcal = 1000 kcal = 1000 kcal =4 184 joules =4. 184 kilojoules.

Mi band's principles:

1, mi band can accurately count steps, which is composed of hardware and software algorithms, both of which are indispensable.

2. The hardware of mi band refers to the built-in triaxial acceleration sensor ADXL362 in MI band. Through this three-axis acceleration sensor bracelet, you can capture the acceleration change of the bracelet in use, thus generating data.

3. In addition, the software algorithm of mi band is three-dimensional data captured by Huami programmers in real time according to three-axis acceleration. After filtering, peak-valley detection and other processes, using various algorithms and scientific and meticulous logical operations, these data are finally converted into readable numbers at the APP end of the bracelet, and the number of steps, distance and calories consumed are presented to the end users.
