Adding Time and Weight Worksheets
How to Add Units of Time and Weight - Time and weight are indeed two physical quantities that have many different units. For instance, time can be measured in seconds, minutes, and hours. Whereas, for measuring weight, we can use units like newton and pounds because weight is different than mass and is a form of force. The addition of the units of time and weight can be a pretty simple task, and in case of different units within a physical quantity, we can just convert those units to make them common and then add. For example, in case of time, if we want to add 3 hours, 2 minutes, and 37 seconds, we can just write it as 3 hours 2 minutes and 37 seconds, or we can convert those units into a common unit and then add. In this case, we can convert all these units into the smallest unit that is seconds and then add. An hour is equal to 3600 seconds, so 3 hours will be equal to 10800 seconds, 2 minutes will be 120 seconds, and then 37 seconds. Adding all these values and we will get an answer of 10,957 seconds.
Back in a Jiffy...
Have you ever heard someone say "I'll be back in a jiffy?" Did you wonder how long that really meant? A jiffy is a unit of time that is equal to 1/100th of a second. Now when someone says they'll be back in a jiffy, time them and see if they really are that fast!
