Technical Background

Definition of Speed
Speed is the ratio of distance to time, showing how much distance an object covers in a given time. In the International System of Units (SI), the base unit of speed is **meters per second (m/s)**.

Conversion Algorithm
Our calculator performs all conversions based on **meters per second**:

**Source unit conversion to m/s**: Multiplying the input value by the appropriate conversion factor
**Conversion to target unit**: Dividing the value expressed in m/s by the conversion factor of the target unit
**Formatting the result**: Displaying the result with appropriate precision and format

#### Accuracy and Reliability
– **Four decimal places accuracy** for all conversions
– **Scientifically validated** conversion factors
– **Continuous testing** and validation
– **Continuous improvement** based on user feedback
