10 millimetres = 1 centimetre so 300 mm = 30 cm.
3.4 centimeters = 34 millimeters
Not a lot. You haven't given the units for those numbers - centimeters, millimeters, inches, etc.
No, it is not - millimeters make up centimeters and centimeters make up meters
1 centimeter=10 millimeters
No, millimeters are much smaller. 10 millimeters make up 1 cm
680 mm
3cm.
1 inch = 25.4 millimeters 3 inches = 76.2 millimeters
Multiplying meters by centimeters by millimeters does not equal liters. Liters are a unit of volume, while meters, centimeters, and millimeters are units of length. To convert between the two, you would need to use the appropriate conversion factors based on the dimensions of the object being measured.
300 centemeters equal up to 3 meters
none a metre is made up of 100 centimeters or 1000 millimeters
The answer is in the question, as they often are. the first and most important thing and engineer or technicial (or anyone living in the modern world) is learn the prefixes for the metric system. The basic ones are very simple. c (cent) = x100 k (kilo) = x1000 M (Meg) = x1000000 G (Gig) = x1000000000 m (milli) = /1000 u (micro) = /1000000 n (nano) = /1000000000 Now look at your question. You have millimeters (mm) and centimeters (cm). Guess what the relationship between them is? Hint, look a few lines up in this answer.
