How do you convert km/h to m/s?

By Ritesh|Updated : November 3rd, 2022

The speed can be converted from km/h to m/s by multiplying 5/18 m/s. The International System of Units defines a meter as the distance unit. The global measurement norm is the International System of Units (SI), also referred to as the metric system. On May 20, 1875, seventeen nations, including the United States, signed the International Treaty of the Meter, which is now recognized as World Metrology Day worldwide.

Conversion

We know that:

1 km = 1000m
1 h = 3600 s

So 1km /h = 1000/3600 = 5/18 = 0.28 m/sec

The provided number is multiplied by 5/18, or 0.28 m/sec, to convert km/h to m/s.

Example:

Speed of bicycle = 90 km/hr

To convert the speed into m/sec, we multiply by 5/18

Therefore, speed of bicycle = 90 × 5/18 m/sec = 25 m/sec

The International System of Units, also known as the SI, is the preferred practical system of units of measurement.
In the process of measuring, a unit is a clearly defined physical amount that we use to compare other numbers. Seven of these numbers, or fundamental units, are defined by the International System of Units, generally known as the SI system.
All SI units are defined in terms of constants that characterize the natural world starting on May 20, 2019.
This guarantees the long-term stability of the SI and creates the possibility for the definitions to be implemented using cutting-edge technologies, such as quantum technologies.
