For example, the recognised unit unit symbol l for the unit litre can be confused with the number 1, therefore it is less confusing to write litre in full. Also, the unit symbol t for tonne may in some circumstances be confused with the imperial ton, so in this instance the unit tonne should then be written in full as well.</div></td></tr> <tr><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"></td><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"></td></tr> <tr><td class='diff-marker'>−</td><td style="background: #ffa; color:black; font-size: smaller;"><div>When unit symbols are raised to various powers, it is only the unit symbol which is involved and to the number attached to it.
