SI – International System of Units. SI - (AKA International System of Units or S.I.) is a measuring system based on units of 10. Math – the language of science Units in the S.I. are: meter (m), which is used for measuring length. liter (l), which is used to measure volume. *
Units in the S.I. are:
Example: change meters to centimeters
1 meter = 10 decimeters = 100 centimeters
1.00 meter = 10.0 decimeters = 100. centimeters
1. Begin on the 1cm mark and make your
2. Subtract 1 from the number your recorded
to get your answer. For example:
1.5cm - 1.0 cm = 0.5 cm
1 centimeter = 10 millimeter
1. Place the graduated cylinder on a flat
2. Read from the bottom of the meniscus
(bubble) at EYE LEVEL.
3. Again you want to estimate.
1. Move all sliders/masses to the left.
2. Check to see if the mark on the moving arm
lines up with the 0 on the balance.
3. Place specimen on pan then move the sliders
until the marks line up at 0.
1. Place the electronic balance on a flat, stable surface indoors.
To making accurate and precise measurements.
