# Why Is Accurate Measurement Important In Science And The Real World?

The only reason you meaure something is because you want to know its length, or area or volume or weight or density or temperature or speed, etc.

If you are not going to accurately measure something then you are wasting your time and energy and maybe money.

You usually only measure something when there is a good reason.

If your kid (or pet) might have a fever, you won't only put your hand on their forehead, you'll get the thermometer out, if their forehead feels hot. Why? Because you want/need to know if your baby is sick.   You don't put your hand on their forehead, say,"oh, that's hot" and go to the emergency room  - you get the thermometer out to take an accurate measurement, so that you know if you kid is sick, trying to stay home from school, or if your hand was cold. Accurately measuring the temperature allows you to know if a doctor, time spent in the waiting room, medical bill, and medicine  are needed.

If you are selling your house, then you want an accurate measurement of the square feet of your home. Why? Because a house with 5000 square feet is worth a lot more money than a house with  2000 square feet and you want that extra money.

When making a cake/cookies, if you do accurately measure flour and sugar, then not only will you have wasted your time, energy, and money, but you will be disappointed ( and have a bad taste in your mouth.)  if you can't accurately measure the temperature of your oven then your cake/cookies won't even survive long enough to be taste-tested.

what if the person who paints the white "yard lines" on a football field didn't care if they were accurate? Wouldn't it screw up the game if the 40-yard line was actually 43 yards or if all the lines were 11 yards apart instead of 10y? What if one side of the field was longer than the other, and YOUR team's goal was on the shorter side?

You you are going to bungee jump, then bungee cord better be shorter than the ground! If the person who paints the depth of the water on the side of the pool doesn't care about accuracy, you are going to be paralyzed after you dive into water that's three feet deep.

what if you are sick in the hospital OR even just having a routine vaccination? The difference between 0.13  and 1.3  of medicine in that shot could mean the difference between life and death.

What if you buy a new computer desk and you can't get it through the doorway of the computer room or the refridgerator doesn't fit between the wall and counter or the dishwasher is taller than your kitchen counter, or the new tv is too big for your entertainment/wall unit? You'll be sorry you measured the space your new appliance/electronic had to fit into wrong

What if you are painting your house and run out of paint half-way through? You're going to wish you had cared more about accurate measurements when you were buying the paint, when your friends and neighbors laugh at your house.

If a cop pulls you over for speeding, you will care how fast you were going and you will be thankful for the speed gauge in your car.
