Convert a density of 0.987 g/mL to the SI unit for density, which is kg/m3.

To convert a density from grams per milliliter (g/mL) to kilograms per cubic meter (kg/m³), we follow these conversion steps:

1. **Convert grams to kilograms**:  
   \( 1 \, \text{g} = 0.001 \, \text{kg} \).

2. **Convert milliliters to cubic meters**:  
   \( 1 \, \text{mL} = 1 \times 10^{-6} \, \text{m}^3 \).

### Conversion calculation:
Given:  
\( 0.987 \, \text{g/mL} \).

Convert to kilograms per cubic meter (kg/m³):

\[
0.987 \, \text{g/mL} = 0.987 \times \frac{0.001 \, \text{kg}}{1 \, \text{g}} \times \frac{1 \, \text{mL}}{1 \times 10^{-6} \, \text{m}^3}
\]

\[
= 0.987 \times 1000 \, \text{kg/m}^3
\]

\[
= 987 \, \text{kg/m}^3
\]

### Final Answer:
The density is \( 987 \, \text{kg/m}^3 \).
