Convert Foot per second to Speed of sound at 20 degrees Celsius
Unit definitions
Foot per second
A foot is a unit of length equal to $0.304\,8 \ \text{m}$. Foot per second is the distance traveled in feet in one second.
Speed of sound at 20 degrees Celsius
The speed of sound in air is $343.21\ \text{m/s}$ at 20 degrees Celsius.
How to convert Foot per second to Speed of sound at 20 degrees Celsius
$$\text{Speed}_{\text{Speed of sound₂₀}} = \text{Speed}_{\text{fts⁻¹}} \cdot 0.0008880860114798519856647533580023892$$
Examples
Example 1
Convert $50.0\ \text{fts⁻¹}$ to $\text{Speed of sound₂₀}$.
$$\text{Speed}_{\text{Speed of sound₂₀}} = 50.0 \cdot 0.0008880860114798519856647533580023892$$
$$\text{Speed}_{\text{Speed of sound₂₀}} = 0.044404$$
$$\therefore \ 50.0\ \text{fts⁻¹} = 0.044404 \ \text{Speed of sound₂₀}$$
Example 2
Convert $75.0\ \text{fts⁻¹}$ to $\text{Speed of sound₂₀}$.
$$\text{Speed}_{\text{Speed of sound₂₀}} = 75.0 \cdot 0.0008880860114798519856647533580023892$$
$$\text{Speed}_{\text{Speed of sound₂₀}} = 0.066606$$
$$\therefore \ 75.0\ \text{fts⁻¹} = 0.066606 \ \text{Speed of sound₂₀}$$
Example 3
Convert $105.0\ \text{fts⁻¹}$ to $\text{Speed of sound₂₀}$.
$$\text{Speed}_{\text{Speed of sound₂₀}} = 105.0 \cdot 0.0008880860114798519856647533580023892$$
$$\text{Speed}_{\text{Speed of sound₂₀}} = 0.093249$$
$$\therefore \ 105.0\ \text{fts⁻¹} = 0.093249 \ \text{Speed of sound₂₀}$$
Example 4
Convert $145.0\ \text{fts⁻¹}$ to $\text{Speed of sound₂₀}$.
$$\text{Speed}_{\text{Speed of sound₂₀}} = 145.0 \cdot 0.0008880860114798519856647533580023892$$
$$\text{Speed}_{\text{Speed of sound₂₀}} = 0.128772$$
$$\therefore \ 145.0\ \text{fts⁻¹} = 0.128772 \ \text{Speed of sound₂₀}$$
Example 5
Convert $165.0\ \text{fts⁻¹}$ to $\text{Speed of sound₂₀}$.
$$\text{Speed}_{\text{Speed of sound₂₀}} = 165.0 \cdot 0.0008880860114798519856647533580023892$$
$$\text{Speed}_{\text{Speed of sound₂₀}} = 0.146534$$
$$\therefore \ 165.0\ \text{fts⁻¹} = 0.146534 \ \text{Speed of sound₂₀}$$
