As we are already discussed about metric system https://www.engineertime.com/2018/12/themetricsystem.html. Below table shows, how can we convert some basic commonly used units.
Topic 1 Area and volume conversion
 convert the units of Area
1 m^{2}

10.76 ft^{2}

1 m^{2}

1.2 yd^{2}

1 ft^{2}

0.09 m^{2}

1 yd^{2}

0.84 m^{2}

1 hectare

2.47 acres

2. Convert the units of Volume
1 m^{3}

35.31 ft^{3}

1 m^{3}

1.30 yd^{3}

1 ft^{3}

0.03 m^{3}

1 yd^{3}

o.76 m^{3}

*1 acre = 4046.856 m^{2}

^{Newton : The SI unit of Force is newton. The formula of force is F = ma,( according to the second law of motion )}
^{Derivation:}
Example If we want to calculate a weight of a person into newton then we have to multiply this 0.102 kg.
50 kg = 50 × 9.8 = 490N
Topic 2 Conversion of newton into kilogram & vice versa.
Conversion in brief
 N to Kg.
 N/mm2 to Mpa
 N/mm2 to kg/cm2
 N/m3 to kg/m3
1. 1 N = 0.102 kg or 1 kg = 9.8 N
2. N/mm2 is equal to Mpa (n/mm2 = mpa)
Derivation.
 Pressure : Force / area (Pressure = Pascal* force=N* Area = m2)
 Pa = N/m2
 m^{2}× Pa = N * (10^{6 }= mega)
 1000,000 mm^{2}^{ }× Pa = N
 10^{6
}× pa = N/mm^{2}
 Mpa
= N/mm^{2 } Hence prove.
= N/mm^{2 } Hence prove.
3.Conversion of 1 kg/mm2 into 1 N/mm2
 kg/cm2 = 9.8 N/100 mm2 ( 1 Kg = 9.8 N * 1 cm = 10 mm)
 kg/cm2 = 0.09 N/mm2
4.Conversion of 1 kg/m3 into 1 N/m3
 kg/m3 = 9.8 N/m3 ( 1 Kg = 9.8 N * 1 cm = 10 mm)
 kg/m3 = 9.8 N/m3
