Unit Conversions & The Metric System



My Trick:

Place 10# with base unit (g, m, L)

Place 1 with different unit (kg, cm, mL etc)

𝐸𝑥𝑎𝑚𝑝𝑙𝑒 1: 𝐻𝑜𝑤 𝑚𝑎𝑛𝑦 𝑚𝑖𝑐𝑟𝑜𝑙𝑖𝑡𝑒𝑟𝑠 𝑎𝑟𝑒 𝑖𝑛 1. 5 𝑙𝑖𝑡𝑒𝑟𝑠?

Base unit: L Different Unit: µ𝐿

1 µ𝐿 6
1. 5𝐿 × −6 = 1. 5 × 10 µ𝐿
10 𝐿




𝐸𝑥𝑎𝑚𝑝𝑙𝑒 2: 𝐻𝑜𝑤 𝑚𝑎𝑛𝑦 𝑐𝑒𝑛𝑡𝑖𝑚𝑒𝑡𝑒𝑟𝑠 𝑎𝑟𝑒 𝑖𝑛 7. 6 𝑛𝑎𝑛𝑜𝑚𝑒𝑡𝑒𝑟𝑠?
Base unit: m Different Unit: 𝑛𝑚 𝑎𝑛𝑑 𝑐𝑚

𝑃𝑙𝑎𝑛: 𝑛𝑚 → 𝑚 → 𝑐𝑚

−9
10 𝑚 1 𝑐𝑚 −7
7. 6 𝑛𝑚 × 1 𝑛𝑚
× −2 = 7. 6 × 10 𝑐𝑚
10 𝑚

, YOU GOT THIS!
