I need to know how to make conversions and compare within the metric system of measurement. Such as 0.75L. is equal to how many mL. I have to do problems like that with length, weight, andvolumn.

What is the same about 200mm, 20cm, 2dm and .0.2m? What is different?

Whot is the totla of 675ML plus 1.75L

To make conversions and comparisons within the metric system of measurement, you need to understand the prefixes used in the metric system. Here are the common prefixes:

1. Kilo- (k): 1 kilo unit equals 1,000 base units
2. Hecto- (h): 1 hecto unit equals 100 base units
3. Deka- (da): 1 deka unit equals 10 base units
4. Base unit: This is the unit of measurement without any prefix.
5. Deci- (d): 1 deci unit equals 0.1 base units
6. Centi- (c): 1 centi unit equals 0.01 base units
7. Milli- (m): 1 milli unit equals 0.001 base units

To convert from one metric unit to another, you will need to multiply or divide by a conversion factor. The conversion factor is a fraction equal to 1, but it allows you to change the units by multiplying or dividing.

Let's take your example: 0.75L is equal to how many mL.

To convert liters (L) to milliliters (mL), you need to multiply by the conversion factor:

1 L = 1000 mL

So, to convert 0.75 L to mL, multiply 0.75 by 1000:

0.75 L * 1000 mL/L = 750 mL

Therefore, 0.75 L is equal to 750 mL.

You can follow a similar process for length and weight conversions by finding the appropriate conversion factors and using them to multiply or divide.

Remember, for length, you have meters (m), centimeters (cm), and millimeters (mm) as common units. For weight, you have grams (g) and kilograms (kg) as common units.

By understanding the metric prefixes and using conversion factors, you can easily convert and compare different metric measurements.
