Convert Gram-force to Millinewton

Gram-force [gf]

Millinewton [mN]

Unit definitions

Gram-force is the force exerted by a mass of one gram in standard gravity ($gₙ$) ($1\ \text{kgf} = 9.806\,65\ \text{N}$).

${10}^{-3}$ newtons equal one millinewton.

$$\text{Force}_{\text{mN}} = \text{Force}_{\text{gf}} \cdot 9.80665$$

Convert $40.0\ \text{gf}$ to $\text{mN}$.

$$\text{Force}_{\text{mN}} = 40.0 \cdot 9.80665$$

$$\text{Force}_{\text{mN}} = 392.266$$

$$\therefore \ 40.0\ \text{gf} = 392.266 \ \text{mN}$$

Convert $80.0\ \text{gf}$ to $\text{mN}$.

$$\text{Force}_{\text{mN}} = 80.0 \cdot 9.80665$$

$$\text{Force}_{\text{mN}} = 784.532$$

$$\therefore \ 80.0\ \text{gf} = 784.532 \ \text{mN}$$

Convert $115.0\ \text{gf}$ to $\text{mN}$.

$$\text{Force}_{\text{mN}} = 115.0 \cdot 9.80665$$

$$\text{Force}_{\text{mN}} = 1127.76475$$

$$\therefore \ 115.0\ \text{gf} = 1127.76475 \ \text{mN}$$

Convert $145.0\ \text{gf}$ to $\text{mN}$.

$$\text{Force}_{\text{mN}} = 145.0 \cdot 9.80665$$

$$\text{Force}_{\text{mN}} = 1421.96425$$

$$\therefore \ 145.0\ \text{gf} = 1421.96425 \ \text{mN}$$

Convert $165.0\ \text{gf}$ to $\text{mN}$.

$$\text{Force}_{\text{mN}} = 165.0 \cdot 9.80665$$

$$\text{Force}_{\text{mN}} = 1618.09725$$

$$\therefore \ 165.0\ \text{gf} = 1618.09725 \ \text{mN}$$
