# Notasi Baku, Prefik, dan Konversi

## Konsep Dasar

#### NOTASI BAKU

$$\large \bbox [5px, border: 2px solid red]{a \times 10^{\text{n}}}$$

$$1 \leq a < 10$$

$$\text{n = bilangan bulat}$$

Contoh 1

$$\text{a.}\:\:\:598 000 000 = 5.98 \times 10^8$$

$$\text{b.}\:\:\:0.0000652 = 6.52 \times 10^{-5}$$

Contoh 2

$$\text{a.}\:\:\:30 000\text{ m} + 24000 \text{ m}$$

$$\:\:\:\:\:\:\:3.0 \times 10^4 \text{ m} + 2.4 \times 10^4 \text{ m}$$

$$\:\:\:\:\:\:\:5.4 \times 10^4 \text{ m}$$

$$\text{b.}\:\:\:0.00856\text{ mm}- 0.00078 \text{ mm}$$

$$\:\:\:\:\:\:\:8.56 \times 10^{-3} \text{ mm} - 7.8 \times 10^{-4}\text{ mm}$$

$$\:\:\:\:\:\:\:8.56 \times 10^{-3} \text{ mm} - 0.78 \times 10^{-3}\text{ mm}$$

$$\:\:\:\:\:\:\:7.78 \times 10^{-3}\text{ mm}$$

#### PREFIK

\begin{array}{cccc}
\color{blue}\text{Prefik} && \color{blue}\text{Simbol} &&\color{blue} \text{Faktor dari 10}\\\\
\text{peta} && \text{P} && 10^{15}\\\\
\text{tera} && \text{T} && 10^{12}\\\\
\text{giga} && \text{G} && 10^{9}\\\\
\text{mega} && \text{M} && 10^{6}\\\\
\text{kilo} && \text{k} && 10^{3}\\\\
\text{hekto} && \text{h} && 10^{2}\\\\
\text{deka} && \text{da} && 10^{1}\\\\
\text{desi} && \text{d} && 10^{-1}\\\\
\text{centi} && \text{c} && 10^{-2}\\\\
\text{milli} && \text{m} && 10^{-3}\\\\
\text{mikro} && \mu && 10^{-6}\\\\
\text{nano} && \text{n} && 10^{-9}\\\\
\text{piko} && \text{p} && 10^{-12}
\end{array}

Contoh:

$$2.5 \text{ nm} =\dotso \text{ km}$$

$$\text{nano} = 10^{-9}$$

$$\text{kilo} = 10^3$$

Kurangkan pangkat 10 dari nano dengan pangkat 10 dari kilo

$$2.5 \text{ nm} = 2.5 \times 10^{-9-3}\text{ km} = 2.5\times 10^{-12}\text{ km}$$

#### KONVERSI

1 kg = 1000 gram

1 kg = 10 ons

1 kg = 2 pon

1 ons = 100 gram

1 ton = 1000 kg

1 liter = 1 dm3 = 0.001 m3

1 liter = 1000 cm3 = 1000 cc

1 ml = 1 cm3 = 0.001 liter

1 menit = 60 detik

1 jam = 60 menit = 3600 detik

1 hari = 24 jam
