How do you convert grams to kilograms?

Back

To convert grams to kilograms, divide the number of grams by 1,000. For example, 1,000 grams is equal to 1 kilogram.

What is the relationship between liters and milliliters?

Back

1 liter is equal to 1,000 milliliters. Therefore, to convert liters to milliliters, multiply the number of liters by 1,000.

How do you estimate the volume of a liquid?

Back

To estimate the volume of a liquid, you can use common containers as references, such as a cup (about 250 ml) or a liter bottle.

Front

What is the formula to calculate the change in temperature?

Back

To calculate the change in temperature, subtract the final temperature from the initial temperature. For example, if it was 80°F and then 50°F, the change is 80 - 50 = 30°F.

Front

How do you measure time in hours and minutes?

Back

Time is measured in hours and minutes. There are 60 minutes in 1 hour. For example, 1 hour and 30 minutes is written as 1:30.

Front

What is mass?

Back

Mass is a measure of how much matter is in an object, usually measured in grams (g) or kilograms (kg).

Front

How many grams are in a kilogram?

Back

There are 1,000 grams in a kilogram.

Front

What is the difference between weight and mass?

Back

Weight is the force of gravity on an object, while mass is the amount of matter in the object. Weight can change with gravity, but mass remains constant.

Front

How do you calculate the duration of an event?

Back

To calculate the duration, subtract the start time from the end time. For example, if a movie starts at 2:15 PM and ends at 4:00 PM, the duration is 1 hour and 45 minutes.
