Key Stage 3

Meaning

Centi is a Unit Prefix that means a number is 100 times smaller than the normal unit.

About Centi

Centi can be shortened to a lower case c.
Centi is rarely used with any units other than metres.

Examples

A centimetre (cm) is 1/100th of a metre (m).
A centilitre (cL) is 1/100th of a litre (L).

Converting from Centi

To convert from centi to the base unit you must divide by 100. \[63000cm = \frac{63000}{100}m = 630m\] \[3500cm = \frac{3500}{100}m = 35m\] \[940cm = \frac{940}{100}m = 9.4m\] \[93cm = \frac{93}{100}m = 0.93m\] \[4cm = \frac{4}{100}m = 0.02m\]

Converting to Centi

To convert to centi from a base unit you must times by 100. \[7m = 7\times100cm = 700cm\]

\[15m = 15 \times 100cm = 1500cm\]

\[8.2m = 8.2\times100cm = 820cm\]

\[0.26m = 0.26\times100cm = 260cm\]

\[0.03m = 0.03\times100cm = 3cm\]

Key Stage 4

Meaning

Centi is a Unit Prefix that means a number is 10-2 times the normal unit.

About Centi

Centi can be shortened to a lower case c.
Centi is rarely used with any units other than metres.

Examples

A centimetre (cm) is 10-2 metres (m).
A centilitre (cL) is 102 litres (L).

Converting from Centi

To convert from centi to the base unit you must times by 10-2. \[63000cm = 63000 \times 10^{-2}m = 630m\] \[3500cm = 3500\times10^{-2}m = 35m\] \[940cm = 940\times10^{-2}m = 9.4m\] \[93cm = 93\times10^{-2}m = 0.93m\] \[4cm = 4\times10^{-2}m = 0.02m\]

Converting to Centi

To convert to centi from a base unit you must times by 102 because there are 100 of them in the base unit. \[7m = 7\times10^{2}cm = 700cm\]

\[15m = 15\times10^{2}cm = 1500cm\]

\[8.2m = 8.2\times10^{2}cm = 820cm\]

\[0.26m = 0.26\times10^{2}cm = 260cm\]

\[0.03m = 0.03\times10^{2}cm = 3cm\]
