Meaning

Converting units is when one unit prefix is switched for another.

About Converting Units

kilo (k) - 1000 times bigger.
centi (c) - 100 times smaller.
milli (m) - 1000 times smaller.
micro (µ) - 1000,000 times smaller.

Kilo

To convert from kilo to the base unit you must times by 1000. \[5km = 5 \times 1000m = 5000m\] \[12kA = 12\times1000A = 12000A\] \[3.4kV = 3.4\times1000V = 3400V\] \[0.53kN = 0.53\times1000N = 530N\] \[0.082kJ = 0.082\times1000J = 82J\]

To convert to kilo from a base unit you must divide by 1000. \[23000m = \frac{23000}{1000}km = 23km\]

\[8200A = \frac{8200}{1000}kA = 8.2kA\]

\[670V = \frac{670}{1000}kV = 0.67kV\]

\[32N = \frac{32}{1000}kN = 0.032kN\]

\[2J = \frac{2}{1000}kJ = 0.002kJ\]

Centi

To convert from centi to the base unit you must times by 1000.

63000cm = (63000/100)m = 630m

3500cm = (3500/100)m = 35m

940cm = (940/100)m = 9.4m

93cm = (93/100)m = 0.93m

4cm = (4/100)m = 0.02m

To convert to centi from a base unit you must divide by 1000.

7m = 7x100cm = 700cm

15m = 15x100cm = 1500cm

8.2m = 8.2x100cm = 820cm

0.26m = 0.26x100cm = 260cm

0.03km = 0.03x100cm = 3cm

Milli

To convert from milli to the base unit you must times by 1000.

83000mm = (83000/1000)m = 83m

2600mm = (2600/1000)m = 2.6m

170mm = (170/1000)m = 0.17m

22mm = (22/1000)m = 0.022m

6mm = (6/1000)m = 0.006m

To convert to milli from a base unit you must divide by 1000.

4m = 4x1000mm = 4000mm

34m = 34x1000mm = 24000mm

1.9m = 1.9x1000mm = 1900mm

0.73m = 0.73x1000mm = 730mm

0.092m = 0.092x1000mm = 92mm

Micro

To convert from micro to the base unit you must times by 1000.

63000µm = (63000/1000,000)m = 0.063m

8400µm = (8400/1000,000)m = 0.0084m

260µm = (260/1000,000)m = 0.00026m

98µm = (98/1000,000)m = 0.000098m

3µm = (3/1000,000)m = 0.000003m

To convert to micro from a base unit you must divide by 1000.

8m = 8x1000,000µm = 8,000,000µm

54m = 54x1000,000µm = 24,000,000µm

6.2m = 6.2x1000,000µm = 6,200,000µm

0.33m = 0.33x1000,000µm = 330,000µm

0.052m = 0.052x1000,000µm = 52,000µm
