The World and The Metric System 🔺

Imperial Measurement to Metric 🔺 1 inch= 2.54 centimeters 🔺 1 foot = 0.3048 meters 🔺 1 mile = 1609.34 meters

Conversions 🔺 Once a number is in the metric system it is easy to convert.

Significant Figures The “Important digits” 1) All nonzero digits are significant. 2) All zeroes between significant digits are significant. 3) All zeroes which are both to the right of the decimal point and to the right of all non-zero significant digits are themselves significant. Round 742,396 to four, three, and two significant digits

Scientific Notation A very large or very small number written in two parts. Just the digits (with the decimal point placed after the first digit) followed by a × 10 to a power that puts the decimal point where it should be. (i.e. it shows how many places to move the decimal point). 5326.6 is written as what?
