==Key Stage 4==
===Meaning===
[[Deci]] is a [[Unit Prefix]] that means a number is 10<sup>-1</sup> times the normal [[unit]].
===About Deci===
: [[Deci]] can be shortened to a lower case c.
: [[Deci]] is rarely used with any [[unit]]s other than [[metre]]s.
===Examples===
: A decimetre (dm) is 10<sup>-1</sup> metres (m).
: A [[Decimetre Cubed|decimetre cubed]] is the same as a [[litre]].
===Converting from Deci===
To convert from [[deci]] to the base unit you must times by 10<sup>-1</sup>.
: <math>63000dm = 63000 \times 10^{-1}m = 630m</math>
: <math>3500dm = 3500\times10^{-1}m = 350m</math>
: <math>940dm = 940\times10^{-1}m = 94m</math>
: <math>93dm = 93\times10^{-1}m = 9.3m</math>
: <math>4dm = 4\times10^{-1}m = 0.2m</math>
===Converting to Deci===
To convert to [[deci]] from a base unit you must times by 10<sup>1</sup>.
: <math>7m = 7\times10^{1}cm = 700cm</math>
: <math>15m = 15\times10^{1}dm = 150dm</math>
: <math>8.2m = 8.2\times10^{1}dm = 82dm</math>
: <math>0.26m = 0.26\times10^{1}dm = 2.6dm</math>
: <math>0.03m = 0.03\times10^{1}dm = 0.3dm</math>
