How to be Accurate with a Tape Measure.
 On Most British Tape Measures, you can see Inches at the Top and Cm/ mm at the bottom. Most Trades People use mm and is the most Accurate. Make sure you do not get Cm and mm mixed up.
 To allow an accurate measurement the hook on the end of the tape measure is taken into account and moves. the Hook Moves to take into account the thickness of the Hook so the measurement is correct if you either hook your tape measure over a piece of wood or but up to a piece of wood
 Measure in a straight line not diagonal. Not measuring in a Straight Line will result in a measurement greater than the true measurement, unless you want a diagonal measurement.
How to Measure Windows
 For double glazed doors and windows measure the opening side on the height and the width. Always measure the exact brickwork not the frame.
 To measure a square bay window, they consist of 2 sides and a front window and 2 x 90degree corner post. Measure the height externally but measure the width of each facet internally.
 To measure a bow window is the same as square bay but with shallow angles and more facets.
How to Convert measurements
 Convert the measurements to meters, (if for any reason you was not able to make the original measurements in meters). If you try to figure your area with measurements in more than one unit of measure, your calculations will be incorrect.
 Divide measurements in millimetres by 1000 to get meters. Therefore, if the object or area you measured is 800 millimetres long, that is 800 / 1000 = 0.80 meters.
 Divide measurements in centimetres by 100 to get meters. Therefore, if the object or area you measured is 80 centimetres long, that is 80 / 100 = 0.80 meters.
 Multiply measurements made in inches by 0.0254 to convert them to meters. Therefore, if your object or area is 12 inches long, that is 12 x 0.0254 = 0.3048 meters.
 Multiply measurements made in feet by 0.3048 to convert to meters. If you measured something 2 feet long, it measures 2 x 0.3048 = 0.6096 meters.
 Multiply any measurements taken in yards by 0.9144 to convert them to meters. So, if the object you measured was 1/2 (0.5) yards long, it would measure 0.5 x 0.9144 = 0.4572 meters long.
How do I know if my Door Frame is Square?
 Measure from the bottom left of the door frame to the top right, write down the measurement. Then measure the bottom right to the top left of the door frame and the measurement should be about the same.
 A few mm difference is square but over 1cm (10mm) difference it is getting to a not square situation.
How to work out the Surface area
 To find the surface area in square meters, multiply the wall length by its height of the whole wall. If you measure your wall and it is 3meters long and 2.25 meters high, then the square meters is 6.75meter² (3 x 2.25).
 Then deduct any areas which are not to be covered i.e., a door way. When deducting for a window reveal (the small wall between a main wall and the actual window) remember to then add on the area to be fitted into the window reveal.
 When tiling for instance most fitters when they have the final measurement will then round up and then add 10%, so if we have a final measurement of 6.75m² we round up to 7m then add 10% =7.7m² then round up again to 8m². When Tiling It is always best to have enough tiles as even though the type and colour might be the same, batches vary in colour (very noticeable in most cases) and finding the same batch of tiles later can be impossible.
