USE IN DAILY LIFE

IN COOKING , WE USE MEASUREMENTS FOR VOLUME WHEN FOLLOWING RECEIPE BOOKS.TOOLS SUCH AS MEASURING CUPS MAY BE USED TO DETERMINE VOLUME. WHEN MAKING CAKE FOR EXAMPLE WE MAY NEED TINS OF A SPECIFIC WIDTH AND LENGTH FOR A PARTICULAR RECEIPE . WE MAY ALSO NEED TO WEIGHT OUT THE WEIGHT OF THE DRY INGREDIENTS USING A MEASURING SCALE .

BEFORE LEAVING THE DOOR WE MAY CHECK THE WEATHER FORECAST . THE TEMPERATURE MEASURED USING THE THERMOMETRE WILL HELP TO DETERMINE WHAT WE WEAR .

WHEN PLANNING A CAR JOURNEY , WE MAY LOOK AT THE MAP TO FIND THE QUICKEST WAY TO REACH A PARTICULAR DISTANCE. WE MAY LOOK AT HOW TO CUT DOWN THE NUMBER OF MILES WE HAVE TO TRAVEL BY TAKING SHORT CUTS. THE SPEED YOU TRAVEL AT CAN ALSO BE MEASURED AND THIS MAY CONTRIBUTE TO THE LENGTH OF YOUR JOURNEY IF YOU TRAVEL FASTER.
