Why Would You Have To Know How To Convert Measurements When Looking At A Technical Drawing?

I am not exaggerating when I say that knowing my units of measurement and conversion factors literally saved my life.

A few years back, nosotros were living in a foreign country and my appendix flared up. Long story short, it had to be removed . . . chop-chop. There was no time to counterbalance me beforehand, so the anesthesiologist asked me how much I weighed.

And I gave my reply in pounds . . . only they didn't use pounds in that particular land.  They used the metric system, which meant that my weight should be given in kilograms.

The doctor replied that there was no way I weighed that much. This time she asked, "What is your weight in kilos?"

Uhhhh . . .

And that'due south when my high schoolhouse chemistry teacher flashed into my heed'southward eye - 1 kilo equals 2.2 pounds.

I did a bit of quick math in my caput and answered her question.  Luckily my math was right, the anesthesiologist was able to give me the correct dose for surgery, and I'1000 here today partly because I knew how to convert pounds to kilograms in a moment.

Now, I know that my story is a bit dramatic and not all of your students will exist in a foreign country needing to convert their weight in an emergency situation. But units of measurement and knowing how to catechumen them is super important to science.

So, I wanted to take a moment to share a flake more than about units, along with some of the key conversion factors your students should memorize. And, then nosotros'll wrap it all up with a free printable you can employ with your students to practice all this.

Sound proficient? Let'southward dig in!

Why are the units of measurement so important?

I am a bit of a stickler on units of measurement thanks to my high schoolhouse chemistry instructor. She ever told us that a number in chemical science meant nothing without its units, which is and so true.

Later all, if I say that I need ii of sugar for a recipe, do you know if I mean 2 tablespoons, 2 grams, 2 cups or two kilos?

That'south why from the very outset time I innovate measurements to my students I ever emphasize the importance of non forgetting to write the units. I know from experience how fundamental information technology is to lay a foundation for remembering these units of measurement early on.

Knowing the units of measurement that stand for with a number can give you then much more information than a digit sitting there by itself. Units can:

• Aid to show another person the exact amount y'all take
• Assist in solving a mathematical problem, specially in chemistry, where you can follow the units to go to the respond
• Show which measurement system the person is using (i.e. metric or standard)

In a nutshell, the unit of measurement in science serves as the supporting pillar upon which a number rests.

What are the 2 main systems of measurement?

There are two primary systems of measurement used in today's nations:

1. The Metric System –This organisation is used in most of the world and it employs units like meters, grams, and liters. The arrangement is base 10 and the names are formed with prefixes. It was derived from i of the early French measuring systems.
2. The Standard or Standard American Engineering (SAE) System –This system is mainly utilized in the Usa and it contains units like inches, pounds, and gallons. It was derived from an early English measuring arrangement that has its roots in the Roman organisation of measurements.

In the United states, the SAE arrangement of units is more widely used on consumer products and in industrial manufacturing, while the metric system is more widely used in science, medicine, and government.

So, it's especially important for American students to be familiar with both systems.  Even so, every student should know how to convert measurements within of their nearly commonly used organization of measurement. In other words, students should be familiar with knowing how to convert grams to kilograms or ounces to pounds.

Key Conversion Factors to Know

Commonly, these conversion factors are taught as a part of their math programme. But, I also recommend that have your students memorize several basic conversion factors betwixt the ii systems as role of their science plan.

Here's what every student should know:

• Pounds to Kilograms: ane kg = two.2 lb
• Gallons to Liters: 1 gal = 3.785 50
• Feet to Meters: ane foot = 0.305 k
• Miles to Kilometers: ane mi = 1.61 km
• Cups to Milliliters: ane c = 240 mL
• Inches to Centimeters: one in = 2.54 cm
• Ounces to Grams: ane oz = 28.3 g

With the global flow of information that occurs these days, it is very important for students to learn these most bones conversion factors.
