Either unit would be reasonable because the coins' diameters can be expressed conveniently either way. US and Canadian nickels are 21.2 mm in diameter, which is the same as 2.12 cm.
one page of a phonebook is measured in mm. unit thickness of a phone book is cm
Milliliters are a measure of volume, millimeters are a measure of distance.
To compare 64 cm and 630 mm, we need to convert them to the same unit of measurement. Since 1 cm is equal to 10 mm, we can convert 64 cm to mm by multiplying it by 10, resulting in 640 mm. Therefore, 630 mm is smaller than 640 mm, making 64 cm the larger measurement.
what unit would you the length of a shoe? mm,cm,dm,m, or km.
1 cm = 10 mm → 3.5 cm = 3.5 × 10 mm = 35 mm
cm
ø 21.21 mm 2.121 cm
To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
Mm
The standard diameter of a US nickel is 21.2 mm so its radius is half that, or 10.6 mm
2.12 cm (or 21.2 mm)
You would measure a nickel in a Graduated Cylinder. Coins are normally measured in grams for weight and mm for diameter and thickness. A U.S. nickel weighs 5 gm, is 21.2 mm in diameter, and is 2 mm thick.
compare it with cm .....mm x 10 cm
one page of a phonebook is measured in mm. unit thickness of a phone book is cm
A US 5 cent coin (a nickel) has a diameter of 21.21 mm -. That is 2.121 cm
2.12 cm (or 21.2 mm)
1 cm = 10 mm. Start with ruler at 0 and mark ribbon at 30 cm. Then place ruler at the mark and measure 30 cm more and make another mark- you are up to 60 cm or 600 mm. Then place ruler at this mark and measure 5 cm, or 50 mm. Now you have a 650 mm ribbon.
