Example of Speed Conversion:
To convert the speed units let’s take an example of speed “Mile/h into km/h”
Convert 15 Mile/h into km/h.
We know that from the table of speed conversion
1Mile/h = 1.60907 km/h
To find the 15 Mile/h simply multiply the 15 with 1.60907
15 Mile/h = 1.60907 × 15
15 Mile/h = 24.136 km/h
Note:

Temperature:
1 | Degree Celsius (oC) | (oF – 32) × 5/9 |
(K – 273.15) | ||
2 | Degree Fahrenheit (oF) | (oC × 9/5) + 32 |
(1.8 × K) – 459.67 | ||
3 | Kelvin (k) | (oC + 273.15) |
(oF + 459.67) + 1.8 |
Example of Temperature Conversion:
To convert the temperature units let’s take an example of temperature “Degree Fahrenheit into Degree Celsius”
Convert 40 Degree Fahrenheit (oF) into Degree Celsius (oC)
We know that from the table of temperature conversion
Degree Celsius (oC) = (oF – 32) × 5/9.
0F is 40 put in this given equation
Degree Celsius (oC) = (o40 – 32) × 5/9.
Degree Celsius (oC) = (8) × 5/9.
Degree Celsius (oC) = 4.4
It means that
4.4 Degree Celsius (oC) = 40 Degree Fahrenheit (oF)

4 | 27.68 | 27680 | 1727.84 | 1 |
Example of Density Conversion:
To convert the density units let’s take an example of density “kg/m3 into lb/ft3”
Convert 5 kg/m3 into cubic lb/ft3
We know that from the table of density conversion
1 kg/m3 = 0.06242 lb/ft3
To find the 5 kg/m3 simply multiply the 5 with 0.06242
5 kg/m3 = 0.06242 × 5
5 kg/m3 = 0.3121 lb/ft3
Note:
Kg/m3 means kilogram/ meter3
