Metric vs. Imperial

Canada is a confusing country when it comes to measuring things. My house is heated to 22, but the pool is at 81. I use one cup of water in my recipe but buy 450 grams of meat.

Why do we do this? What does it mean?

Simple present tense.

Let’s review the simple present tense.

When: to describe a habit or permanent action (fact) or likes and dislikes.

How: For most subject pronouns, do not modify the base form of the verb. For the 3rd person singular pronouns (he, she, it) add an “s” to the verb.

I learn                          She learns

We walk                       It walks

Spelling exceptions:

Verb that ends with a consonant + y                                 try – tries

Verb that ends with x, ch, sh, ss                                         kiss – kisses

Affirmative                           Negative                                     Interrogative
I work                            I do not (don’t) work                      Do you work?
He works                      He does not (doesn’t) work          Does he work?

Don’t forget that the verb “to be” has its own form.

I am                                        I am not                               Am I?
you are                                   you are not                         Are you?
She/he/it is                           she is not                            Is she?

Reading

Lena: Mom, our science teacher said we need to know both metric and imperial systems. I’m confused!

Jay: Yeah, we measured our height in centimeters at school, but I thought we used feet and inches.

Mom: That’s a great question. Let me help. There are two main systems: metric and imperial.

Lena: What’s the difference?

Mom: The metric system is used in most countries. It uses metres for distance and height, kilograms for weight, and litres for liquids. The imperial system, used in the United States and a few other places, uses feet and inches for height, pounds for weight, and miles for distance.

Jay: So I’m 5 feet 7 inches. What’s that in centimetres?

Mom: There are 12 inches in a foot.
5 feet = 60 inches
60 + 7 = 67 inches
Each inch is about 2.54 centimetres.
67 × 2.54 = about 170 centimetres.

Lena: And for weight?

Mom: 1 kilogram is about 2.2 pounds. So if someone weighs 50 kilograms, they weigh about 110 pounds.

Jay: Got it! What about distance?

Mom: In the metric system, we use metres and kilometres.
In the imperial system, we use yards and miles.
1 kilometer is about 0.62 miles.
1 mile is about 1.6 kilometres.

Lena: So if we walk 3 miles to school, that’s about 4.8 kilometers?

Mom: Exactly! You just multiply 3 by 1.6.

Jay: That’s cool. I didn’t know that.

Mom: It’s important to know both systems. You’ll see metric more in science and around the world, but the imperial system is used here in everyday life.
