—More on metric prefixes | Wiki—Wikipedia Jan 1 2018:
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or fraction of the unit. While all metric prefixes in common use today are decadic, historically there have been a number of binary metric prefixes as well.[1] Each prefix has a unique symbol that is prepended to the unit symbol. The prefix kilo-, for example, may be added to gram to indicate multiplication by one thousand: one kilogram is equal to one thousand grams. The prefix milli-, likewise, may be added to metre to indicate division by one thousand; one millimetre is equal to one thousandth of a metre.

Decimal multiplicative prefixes have been a feature of all forms of the metric system, with six dating back to the system's introduction in the 1790s. Metric prefixes have even been prepended to non-metric units. The SI prefixes are standardized for use in the International System of Units (SI) by the International Bureau of Weights and Measures (BIPM) in resolutions dating from 1960 to 1991.[2] Since 2009, they have formed part of the International System of Quantities.

I can't understand why some teachers won't explain it as simple as you did. I am seeing hope now. Thanks so much!

[PT-dgiy]

Wow! you made this so incredibly easy! I spent four hours in class trying to figure this out, but here you are teaching it to me in less than five minutes. You rock!

[jenelope]

Your explanation was literally the best! I finally understand conversions now. Thank you so so much for this video! :)

[meliasmith]

THANK YOU JESUS, THIS IS THE ONLY VIDEO THAT MADE SENSE

[leahm]

You are a Saint! I've been struggling with this since gr 4 and my university ass only decided to sort this out now

[ofekbar]

I wish the lecturers at my university who teach me, will teach as you teach. Well done to you, adore people like you.

I just saw this video for the first time and I think it very helpful, one thing I realize he did not mention the invisible minus you have to use to get the sign right that would help you recognize which side to go when you calculated. Great job!

Thanks so much! I just came up with something weird (but that makes it easier to remember!) for remembering the order of the metric units:
Thank God Man Kind BASEically Dodged Comets Made of Microscopic Ninja Pilots = 
Tetra Giga Mega Kilo BASE UNIT Deci Centi Milli Micro Nano Pico =
Exponents: 12, 9, 6, 3, 0, -1, -2, -3, -6, -9, -12
;) Hopefully you'll imagine microscopic ninjas on comets that mankind dodged and thus, remember the order of the metric units. Worked for me!

Omg thank you! I literally have a test on this in a couple of minutes and this video made so much sense!! thank you so much!

[sandradavis]

Wow! You make a concept that is easily so complicated and make it more digestible, that’s a gift! Thank you 🙏🏽

[generalmaul]

This video is so compact.

Unit conversion is such a headache for me but I'm getting it now.

You're an amazing teacher - thanks so much for explaining everything so clearly!

[angelbautistacarranza]

Thank you 😭 I couldn’t erase my head around this, you just made it A LOT easier.

[Shivam-hqnm]

I am from India I watched more than 1000 video on this topic by Indian teacher but finally my concept is crystal clear only becoz of uhh sir thank you so much ❤️ love you sir

[Savannahhh._.]

You have no idea how I have been trying to find a decent video I could actually understand. Thank God for you!!!!

[preeani]

Omg. Thank you so much. Was unable to convert the units coz of the 1/10 = 1cm fractions coming into picture after the base unit. Logic was defying me. After watching n number of videos was still unable to do the conversions. Urs was the only method which gave me clarity. After watching ur video, conversion sums became a cake walk for me. Hats off to you.

[oh]

Thank you so much! I have a test on the metric system this Friday and I didn’t understand it until I found your video! Thank you so much!!

[dfue]

2 years I’ve been trying to understand this!!! And you taught me in 5 minutes didn’t even have to rewatch the video I’m crying tears or joy 😭 I will share with everyone I love

[PancakeAkechi]

I have a physics midterm tomorrow and this is BY FAR the best video on this. tysm!

[gabejohnson]

Dude, you have no clue how helpful this is for me. You're a lifesaver!

[ehfhejdfhhehd]

you sir explained this in the crystal clearest way possible, thank you so much
