Centimetres

Hmmmm today’s dictionary word is centimetre.
I reckon someone who grew up knowing centimetres and kilometres and the like has it easier than one like me who grew up with feet and inches and had to convert to centimeters.  Like I know I am about 5 foot 8 inches.  I have no idea what that is in kilometres.
I have a pile of tools handed down to me from my dad.  He was into carpentry having worked in a timber yard all his life.  He started out sweeping the office and ended up a manager in another town.
He used to work on big projects at home.  Merril jokes that some of the tools were great for building an ark.  I do remember him building a shed and moving it into place on rollers.  It was huge but he worked out a way to move it into place.  I was impressed.
The thing is though although I have them, they are in imperial rather than metric.  When it comes to nuts and bolts often they are just a different size than what is used currently.  They are not interchangeable.  I need to use one or the other and mostly go with what is current as I can easily get more when needed.
Some things like plainers, spit levels, and plyers and the like are ok no matter the item or distance.  Like spirit levels.  Something is either level or it is not.  Yet the tape measures I have at best give both inches and centimetres.  That is handy as much built was built before centimetres were considered.
What I have done with some of the smaller items is arrange them as museum pieces.  That is, I display them. 
A number of other tools just sit.  And sit.  And sit.  I have never used them but have kept them.  We are at the stage of “why?”  We are happy for them to go to a good home.  But accessing and sorting them is on our “to do” list.  It is closer than it ever was but nothing has changed as yet.
