Length Units

[Perla Cervantes_1G]

As Dr. Lavelle mentioned during lecture today, the SI unit for length is measured in meters (m). However, he also mentioned that we would need to utilize these SI units to convert them into other units depending on the type of problem. My question is: when not specifically asked for the answer in a certain kind of unit, should we automatically infer that SI units are the default means of quantifying something?

[nikitasridhar_1b]

I think so

[nicolesalcedo]

Yeah, I think that we do automatically infer that we answer in SI units since he went over SI units in lecture and since they apply to scientific notation.

[Alexis Bravo 1D]

Yes, when the units are not specified I think we would always answer the question in SI units.

[Michael Park]

Yes. But the correct units they want should be specified within the question.

[MadelynNguyen1F]

Yes, but the question should specify the units you need.

[Jack Martinyan 1L]

Stick to the SI units, unless a question asks for a specific type of unit.

[Molly Oakes 1A]

Yes, I would default to SI units.

[Heung Ching Chia 1E]

Yes, you should use SI units unless otherwise specified explicitly in the question.

[Adam Yaptangco 1D]

I would use SI units in the answer unless explicitly asked for a specific unit.

[yazminedesan1F]

typically yes you should use SI units

[SamanthaGrohe1B]

I agree, usually the question will specify the units to convert to or start your conversions with.

[Mohamad 1J]

Hey Perla,
Yes, the safest bet would be to always put the answer in proper SI units. Unless specifically said otherwise in the question.

[Chem_Mod]

It really does not matter as you have the correct units with the right number as they mean the same thing. If you want to default to SI units, that is also fine.

[Porus_Karwa_2E]

Typically, yes we should just infer that we are supposed to use SI units

[Madeline Motamedi 4I]

This is a bit embarrassing, but I was wondering if anyone knows of the the best way to memorize conversions between various units. Do you guys have any videos or resources for me to memorize?
